Pool Chemicals

Water Balance

It may surprise you, but the water you drink may not be suitable for your pool.  Tap water can have a high or low pH and mineral levels that can harm your pool.  Improper levels of pH and minerals can also prevent pool chemicals from doing their job effectively, not to mention damaging your pool and its equipment with stains, scale and corrosion. So even if you fill your pool from the tap, it will need to be chemically balanced.

In addition to balancing your pool water after the initial fill, it’s a good idea to have your water balanced at the beginning of each swimming season and then get us to check it once a month.

pH

The most important water balance test is pH.  A low pH reading indicates that the water is too acidic, which causes chlorine to be used up too quickly and leads to corrosion of equipment and damage to pool surfaces.  A high pH reduces chlorines effectiveness, can cause cloudy water and scale formation on equipment and surfaces.

Total alkalinity

The correct total alkalinity will make your water’s pH level much easier to maintain. If the total alkalinity is low the pH will fluctuate and the water could become corrosive.  If the total alkalinity is high the pH will be difficult to change and a bicarbonate scale could appear on the heater, within pipe-work and on pool surfaces.

Calcium Hardness

This term is used to describe the amount of dissolved calcium in pool water.  The ideal level is approximately 175 – 275mg/l depending on the pool finish. High calcium hardness levels can cause cloudy water and scale. Low levels can harm the pool and its equipment.

Minimise Chlorine Loss to Sunlight

The sun’s rays can act like a magnet and draw chlorine from your pool water, this can be reduced by applying BioGuard® Stabiliser. Because BioGuard® offers stabilised forms of chlorine, a separate stabiliser is normally only necessary when the pool is drained and refilled.  If you are unsure whether you need to add stabiliser or not, bring a water sample to us for analysis.

Easy as 1-2-3

After your pool water has been balanced correctly regular maintenance is really very simple when you use the BioGuard® 3-Step Programme.

Step 1
Sanitise to kill bacteria continuously using one of the BioGuard® Sanitisers to protect swimmers and keep the water healthy.  We will be able to advise you on the best sanitiser for you and your pool.  For further information on the choice available please go to the Pool Chemicals section within the Chemicals & Water Testing area of the site.  Whichever sanitiser you choose, the aim is to maintain a sanitiser level, (see table below), in your pool 24-hours a day, 7-days a week.

Test Pool Finish Ideal Level (mg/l)
Free chlorine All 1 – 3
Total chlorine All 1 – 3
Bromine All 2 – 4

Chlorine – the chlorine in the water that is effective in killing bacteria is called “free chlorine” or “free available chlorine”.   If you are using BioGuard® 4-Way Test Strips or the BioGuard®
1200V Test Kit you will be testing the free chlorine level. When you bring a water sample to us we will test for both free chlorine and total chlorine, this is done so the level of chloramines can be determined.  Chloramines are undesirable compounds formed when chlorine combines with nitrogen and causes eye and skin irritation, as well as unpleasant odours.

Bromine – like chlorine is effective in killing bacteria. Bromine is ideally suited to indoor pools
that are run at higher temperatures.

Step 2
Remove wastes and add sparkle to your pool water with BioGuard® Burn Out Lite.  This
treatment, sometimes referred to as “shocking” or “oxidising” the pool, is applied weekly. It can also be applied after the pool has been heavily used or after heavy rainstorms.  What the treatment does is help the chlorine and filtration systems keep the water sparkling and free of water soluble wastes such as cosmetics, perspiration, urine and suntan lotion.

When wastes build up in the water, particularly after the pool has been used by a lot people, the effectiveness of chlorine is reduced.  Because the wastes dissolve into the water, the filter cannot remove them.  The nitrogen in the wastes then combines with chlorine to form chloramines.  Chloramines are the cause of chlorine odour and irritation. 

Many people think that too much chlorine causes odour and irritation.  That’s not true. It’s the chloramines formed by wastes in water that cause the problem.  Wastes also make the water look dull and become cloudy.  They also leave the pool vulnerable to algae infestation.  A simple treatment of BioGuard® Burn Out Lite will clear your water of wastes quickly.

Step 3
Prevent algae from appearing in your pool with a weekly addition of BioGuard® Algae Inhibitor. Algae are microscopic plant life that multiply rapidly.  You may have seen algae in stagnant ponds.  It often appears as a slimy, green floating and clinging mass.  Other forms of algae are black or mustard-yellow. They enter your pool from rain and wind, even on swimwear and cleaning equipment.

At first, you won’t even notice algae in your water.  Hundreds of thousands of spores can be invisible to the naked eye.  But, almost overnight, your pool can turn into a swampy green mess because of rapid multiplication and growth.  Algae attach to pool surfaces, cloud the water, and clog your filter.  By the time you see them they are well established and will cost you time and money to rid the pool of them.  That’s why algae prevention is  always better than having to cure algae problems.  A dose of BioGuard® Algae Inhibitor is a very worthwhile investment.  Used weekly after your application of BioGuard® Burn Out Lite, a treatment of Algae Inhibitor will prevent a wide species of algae ever gaining a foothold in your pool.

How to Start

Now that you understand what you will be doing to care for your pool on a regular basis, let’s look at how you start your pool when it’s first installed or at the beginning of each swimming season.  The right start can make all the difference to how easy your pool is to maintain.

With BioGuard®, the right start is easy, just follow these simple steps:

  1. Fill your pool.  If the pool was closed for the winter and the water level is low, top up the water level to the middle of the skimmer opening.
  2. Remove your pool cover.  If your pool is new skip this step. If your pool has been covered with a winter debris cover sweep it and clean it with BioGuard® Stowaway to prevent mildew and unpleasant odours.  Once it is clean, store the cover in a clean, dry place, away from sunlight and weather.
  3. Check your pump skimmer basket and filter.  Make sure all equipment is clean and in working order.  Start the circulation system and remove debris from the pool.  Your filter is a very important part of your pool maintenance programme.  If it is not working properly, neither will the chemical products you add. If the filter media is dirty or wasn’t cleaned before the pool was closed, remove grease, oil and scale deposits by using BioGuard® Deep Cleanse.
  4. Have your water analysed here at Barton Lake.  Using a clean plastic container, or one provided by your dealer, take a 1-litre pool water sample, by dipping the container to about elbow-depth.  Seal the container to avoid leaks and bring it in.  We have an advanced lab and computer, so you can get accurate and personalised information that tells you just what your pool needs for start-up.
  5. Test chlorine and pH. Once you have followed the instructions of your BioGuard® water analysis to get your pool up and running, use your BioGuard® 4-Way Test Strips or 1200V Test Kit to check the free chlorine and pH levels.  When you have achieved a free chlorine level of 1 to 3mg/l and a pH level between 7.4 and 7.6, you’re ready to swim.
  6. Now that you’re swimming. Start routine maintenance using the BioGuard® 3-Step Programme and follow the easy maintenance calendar.

What’s Wrong?
When you use BioGuard® products and follow your dealers advice, problems with your pool water should be rare.  If something does go wrong, this section will help you identify the problem and find a quick solution.  When it comes to specific questions or concerns about your pool, your best source for advice is here at Barton Lake.  The quickest way to get an accurate diagnosis and proper treatment for problems is to bring a water sample to us.

CLOUDY WATER
If you use BioGuard® your pool should be so clear that you can make out whether a coin on the bottom is heads or tails.  If you can’t, one of several things could be wrong.

Check your circulation and filtration system, is the flow from the inlets powerful enough, or does it seem weak?  How many hours a day is the filter operating? The filter must be in proper working order, with clean filter media and the pump should be running for at least 8-hours a day - longer when the pool is being heavily used. Solution: Increase the filtration running time to 24-hours per day until the water clears.  To assist the filter in removing fine particles use BioGuard® Polysheen Blue, Super Clear Tablets or Kwik Clear.

How long is it since the filter media was cleaned?  To clean dirty filter media use BioGuard® Deep Cleanse which will remove grease, oil and scale.  Check the chlorine level, is it below 1mg/l. Are chloramines present?  If the sanitiser level drops then bacteria and algae may invade, or organic wastes can build up, causing water to cloud and lose its sparkle.  Solution: Add BioGuard® Burn Out Lite and maintain chlorine level at 1 to 3mg/l, 24-hours a day, 7-days a week.

Check pH and total alkalinity.  Is the pH too high?  If the pH of the water is over 7.6, it may cause cloudiness and scale build up. Is the total alkalinity high?  If the total alkalinity of the water is over 150mg/l, it can cause cloudy water and scale formation. Solution: Monitor pH and total alkalinity and adjust as necessary.

Check for algae.  Are algae visible?  Are the walls or other fixtures slick or slimy?  Algae growth in its early stages may not be visible, or it may show up as black or mustard spots on the pool surfaces.  Algae may be the source of cloudy water.  Solution: Shock dose the pool with BioGuard® Bio Shock Xtra or BioGuard® Bio Shock and use BioGuard® Erase to destroy algae.

Check other water balance factors.  The best way to check water balance is through us.  The detailed analysis that we can do on your behalf includes factors like calcium hardness and total dissolved solids, which may be the cause of cloudy water.

COLOURED WATER
Once you have seen the way your pool looks when maintained properly, you’ll know that it should be sparkling, clear and blue.  When the water is off-colour, a problem is lurking.

Green water: 
Is the water cloudy and green?  Solution: See algae section below. Is the water clear and green?  Solution: See metals section below, the problem is likely to be copper.

Other colours:
Water can turn reddish-brown, grey or coffee-brown because of the presence of metals such as manganese, copper or iron.  Solution: Have your water tested by us for trace metals and if any are found treat the water with BioGuard® Stain and Scale Inhibitor.

METALS AND STAINS
To remove fresh stains and eliminate coloured water, use BioGuard® Stain and Scale Inhibitor and Kwik Clear.  To prevent stains, keep your pool water balanced and have your water tested once a month by your BioGuard® dealer.  The test will reveal whether metals are present and help prevent problems with stains.

ALGAE
When you see them, you will already have about 30 million algae per 32ml of pool water.  Luckily, BioGuard® has a treatment for all types of algae – from green slime to mustard-yellow to black spot.

Green algae:
Green algae are one of the most common problems for pools.  It usually appears in corners or other areas where circulation is poor.  Once established green algae can multiply rapidly.  Solution: Check pH level (algae can push the pH level up), shock dose the pool using BioGuard® Bio Shock Xtra or BioGuard® Bio Shock and then treat with BioGuard® Erase.  For a full algae treatment routine see the table below:

Mustard Algae:
Another common algae in pools, which gets it name because of its mustard-yellow colour.  It brushes off the walls and pool floor easily, but quickly returns.  It often grows in shady areas or areas of poor circulation.  It resists chlorine and shock treatments.  Solution: See table above.

Black Spot Algae:
A very resistant form of algae that clings to the pool walls, floor and cracks, black spot algae is so named because it forms clumps of algae spots that sometimes resemble ‘tar spots’.  The longer
black algae are present, the more treatment will be required and the longer it will take to get rid of them.  Solution: Brush vigorously to break the tops then follow procedure for green algae destruction.

Back to Top

SCALE
Rough, sandpaper like deposits can coat the walls of your pool, clog pipes, filters and heaters.  Solution: Check water balance and maintain within the ideal levels.  Use BioGuard® Stain and Scale Inhibitor to prevent scale deposits appearing.

Eye and Skin Irritation / Chlorine Odour:
When you notice a strong chlorine odour and the water is irritating to eyes or skin, it isn’t necessarily the chlorine that is to blame.

Check Chloramines.  Having your water analysed by us may reveal chloramines (combined chlorine).  Solution: We can recommend the necessary dosage of BioGuard® Bio Shock Xtra or BioGuard® Bio Shock required to get rid of the chloramines.

Check pH.  Low pH can be the cause of eye irritation.  Solution: Raise pH level using BioGuard® Balance Pak 200 to within the ideal range.  High pH can be the cause of skin irritation. Solution: Lower pH using BioGuard® Lo ‘n’ Slo to within the ideal range.

CHLORINE DEMAND
There are many reasons you may not be able to maintain a proper chlorine level. 

Check filter:
Your filter must run for at least 8-hours per day or there will not be enough chlorine distributed in the water to kill bacteria.  Solution: Make a point to keep your filter operating for a minimum of 8-hours a day and longer when the pool is being heavily used.

Check Chlorine:
If there isn’t enough chlorine in your skimmer or chlorinator or if your automatic chlorinator is not working properly, you may get a low reading.  Solution: Make sure you replenish chlorine and check for blockages in chlorinator lines.

Check for algae:
Algae will cause a dramatic increase in the amount of chlorine your pool uses.  Look for signs of low circulation areas, cracks and crevices.  Solution: Bring a water sample us and get a water treatment recommendation.

Check water balance:
When water is not properly balanced, more chlorine is consumed.  Solution: Balance your water to within the ideal levels.  Keeping the water balanced allows for more efficient use of chlorine.

Check for high chlorine:
Sometimes, your test kit reading will indicate that you have no chlorine when you actually have too much.  What happens is the high levels of chlorine bleach out the DPD1 tablet making it appear that there is no chlorine present.  Solution: Usually, high levels of chlorine will dissipate quickly.  However, if the condition persists for more than two days, visit us for some BioGuard Chem –Out, which can be used to reduce the chlorine level.

Check test kit reagents or test strips:
The test kit reagents or test strips used for performing the tests can deteriorate over time.  Solution: Replace reagents at the start of each season to ensure accurate testing.  Check the expiry date on the test strips and if it has passed replace the strips. 

Other problems:
If you have checked all the other factors that can affect the level of chlorine in your pool or your test kit reading, you may have a different problem.  Solution: Take a water sample to your dealer for analysis.  Shock treat your pool with BioGuard® Bio Shock Xtra or BioGuard® Bio Shock using the problem solving dose rate on the product label (this should increase your chlorine level by approximately 10mg/l) and leave for 24-hours, retest pool and if the chlorine level has dropped by more than 3mg/l, repeat shock treatment.  Keep repeating this process until after a 24-hour period the chlorine level does not drop. Keep an eye on your pH level during this process as it may increase and you will need to adjust it as necessary to achieve the ideal level.  Do not let pool usage recommence until the chlorine level is 5mg/l or lower.

SEASONAL CHANGES
In the U.K. most outdoor pools are only used during the summer.  At the end of the swimming
season pools are shut down for the winter.  This is called “closing down” or “winterising” the pool.

It’s important to close your pool properly to protect it from damage caused by freezing and other problems that can occur in the water during the winter. 

When you close your pool the right way with BioGuard® it will be easy to get it ready to open in the spring when the warm weather returns. 

The quick way to winterise.  Bring a water sample to us and we’ll prepare a personalised prescription that makes closing easy.  When you follow the prescription you will not experience problems with stains, damaged equipment and ‘swampy’ water.  That way you avoid expensive and time consuming repairs and clean up.  If you don’t want to close your pool yourself, we do offer a service to close it for you.

Winterising Step-by-Step

Once you have your water analysed by us, you will have specific instructions for closing your pool.  All the steps are outlined on an easy to follow computer printout.  BioGuard® also offer a chemical winterising pack with an algaecide specifically designed for winter use.  To achieve the best results it is recommended that the pool is not winterised until the water temperature drops to 10 °C.

Here are the steps that you should take when closing your pool:

  1. Get your water balanced.  Your water may already be balanced, but you will find out for sure when you bring a water sample to us for analysis.  If the analysis shows that treatment is needed, follow the our instructions.  Once any adjustments have been made the water has to be circulated.  Test the pH again to be sure it is in the ideal winter range of 7.6 to 7.8.
  2. Clean up.  Brush the walls of your pool, then vacuum well.  Clean the waterline with BioGuard® Off The Wall.  Empty and clean skimmer and pump strainer baskets.
  3. Backwash or clean the filter thoroughly.  If your filter media has not been cleaned recently, use BioGuard® Deep Cleanse as per the instructions on the box and bottles. Never close down the pool leaving dirty filter media as deposits and scale harden and toughen over winter, making it more difficult to remove in the spring.
  4. Add a winter shock treatment.  Shock dose the pool using BioGuard® Bio Shock Xtra or BioGuard® Bio Shock at the rate of 400g per 50m3. After adding the treatment according to the label directions, run your pump for several hours to distribute it evenly.
  5. Protect the pool from algae.  When your pump and filter are not operating, it’s easy for algae to take hold.  Prevent this by using the BioGuard® Hibernate Kit as per the directions on the box and labels.  Run the pump and filter to circulate the water before going to step 6.
  6. Partially drain the pool or not?  All pools are different and because of this we recommend that you speak to us about whether or not to partially drain your pool.
  7. Prepare equipment for winter.  Again we would recommend that you speak to us about the best way to prepare your pool equipment for winter.
  8. Cover your pool.  A well designed pool cover will keep your pool relatively free of leaves and debris making it easier to clean your pool when spring arrives.

Running your pool under the cover. In milder climates, some people choose to cover their pool to keep it clean and lessen maintenance but continue to operate the pump and filter as normal. If you do this, still treat as above but eliminate steps 6 and 7.

Frequently Asked Questions
Q. How long do I have to wait
between different chemical
additions to my pool?
A. Thoroughly read and follow all safety and application instructions on each product container before use. Then, as a general guide, you should allow at least one (1) hour between different chemical additions.
Q. I have just added chemicals to
my pool, when can I start using it?
A. With the pump running, allow a minimum of 2-3 hours for the chemicals to be thoroughly circulated throughout your pool. Re-test your pool using the 4-way test strips and as long as the pH and sanitiser levels are within the recommended ranges, the pool can then be used.
