POOL MAINTENANCE
SIMPLE POOL CARE
Maintain pH at 7.0-7.2 in fibreglass pools and 7.2-7.6 in marbelite pool. Check weekly. Run the pool filter for 12 continuous hours per day in summer, 6-8 continuous hours per day in winter. Shock treat in adverse conditions (wind, rain, heat and heavy pool usage) with 3 cups of HTH® Classic, or one sachet of HTH® Shock It®, for every 50 000 litres of water. Ensure the Total Alkalinity is kept between 80 and 120ppm. Check monthly. Clear out pump and weir baskets, brush pool walls and floor weekly. Backwash, once every two weeks or when you automatic pool cleaner becomes sluggish. Remember to rinse after backwashing.

Chlorination
For stabilised pools, add 1 cup of granular HTH® Classic every second evening or as often as required to maintain a chlorine residual of 1,5-3ppm. For non-stabilised pools, add 1 cup of granular HTH® Classic every evening or as often as required to maintain a chlorine residual of 1.0-1.5ppm.

Testing your Pool water
Regular testing of your pool water is essential so it makes sense to keep testing as simple as possible. There are a number pool test kits on the market, but for ease of use you'll find it hard to beat HTH® Quick Test® Strips. Here's how you use them to check pH, Free Available Chlorine, Total Alkalinity, and Stabiliser levels in your pool water. *Always test pool water in the early evening. Dip a strip into water and remove immediately. Hold strip level for 15 seconds - do not shake off excess water. Compare Free Chlorine, pH, Total Alkalinity and Stabiliser (in that order) to the colour charts on the side of the bottle. Note: For best results on the stabiliser test, the pH should be between 7.0-8.4 and Total Alkalinity should be below 240ppm.

ADJUSTING PH
If pool pH is too Low
If the pH is lower, or has been lower than 7.2 first add 1 litre of HTH® Iron & Metal Remover to the pool. (Follow label instructions.) Add 250g of HTH® Alkalinity Up around the sides of the pool with the filter running. Let the filter run for 3-4 hours and recheck the pH. If the pH is still too low, then repeat previous step and recheck, until pH is within the required range.

If pool pH is too High
Add 1 litre of HTH® Iron & Metal Remover. (Follow label instructions.) Add 250g of HTH® Dry Acid or 250ml Liquid Hydrochloric Acid around the sides of the pool with the filter running. Let the filter run for 3-4 hours and recheck the pH. If the pH is still too high, then repeat previous step and recheck, until pH is within the required range.

ADJUSTING TOTAL ALKALINITY
Total Alkalinity (TA) is simply a measure of all the alkaline substances in your pool water. Once your pool's Total Alkalinity has been established within the ideal range it should only require monthly testing and occasional adjustment

If pool TA is too Low
Add 1 litre of HTH® Iron & Metal Remover to the pool. (Follow label instructions.) Switch the pool motor off. Add 1kg of HTH® Alkalinity Up in one spot in the deep end of the pool, away from metal fixtures. (1kg of HTH® Alkalinity Up should increase the ppm by 10.) Leave the pump motor off for 15 minutes. Then switch the pump motor back on and continue with normal filtration and chlorination. Only check the TA level again after 3-4 days. Repeat the above steps at 3-4 day intervals until the TA is within the recommended range of 80-120ppm. Increasing the TA can be a slow process but once correct, TA need only be checked once a month.

If pool TA is too High
Switch the pool pump motor off. Add 500g/500ml of HTH® Dry Acid or Liquid Hydrochloric Acid in one spot in the deep end of the pool, away from metal fixtures. Leave the motor off for 15 minutes. Then switch the motor on and continue with normal filtration and chlorination Only check the TA level again after 3-4 days. Repeat the above steps at 3-4 day intervals until the TA is within the recommended range of 80-120ppm. pH should never be allowed to drop below 7.0

8 EASY STEPS FOR POOL MAINTENANCE
1. 2. 3. Check pH weekly. Maintain between 7.2 - 7.6 for marbelite pools, and 7.0 - 7.2 for fibreglass pools. Check Total Alkalinity monthly. Maintain between 80 - 120 parts per million (ppm.) Maintain effective chlorination. For stabilised pools, add 1 cup of Granular HTH® Classic every second evening or as often as required to maintain a chlorine residual of 1.5 - 2.0ppm. For non-stabilised pools, add 1 cup of Granular HTH® Classic every evening or as often as required to maintain a chlorine residual of 1.0 1.5ppm. 4. Shock treat monthly as part of regular maintenance program. Add 3 times the normal dose of Granular HTH® Classic. When using a Stabilised Product (pills/floaters) - every 7-10 days. When using a Non Stabilised Product (Granular HTH® Classic dry chlorine) - monthly. 5. 6. 7. 8. Remove debris. Clear pump & weir baskets weekly. Brush pool walls & floors weekly. Run the filter for 12 continuous hours per day in summer and 6 - 8 continuous hours per day in winter. Backwash at least every 2 weeks or when the automatic pool cleaner becomes sluggish. Remember to rinse after backwashing.

POOL TREATMENTS
No matter what type of product or system you choose to keep your pool water sparkling clear and healthy, HTH® Pool Assist can help you.

Chlorine-free products
If you have been using chlorine free products in your swimming pool and want to revert back to using chlorine pools, call HTH® Pool Assist for a specialised treatment.

Salt Chlorinators
Salt Chlorinators produce chlorine through a process of electrolysis, so pool water chlorinated this way may be boosted or shock treated with Calcium Hypo chlorite (granular HTH® Classic Chlorine). This is highly recommended to help the chlorinator cope with adverse weather conditions or loads of swimmers using the pool.

Copper Ioniser
Copper ionisers are electronic devices which release soluble copper ions into the water. Copper salts perform well in the destruction and prevention of algae. However, copper is a poor bactericide when compared with chlorine, therefore it is still necessary to use chlorine to sanitise the swimming pool water. A drawback of using copper is staining.

POOL RENOVATIONS
Your swimming pool is a major investment. Apart from giving you and your family hours of pleasure, it upgrades the value and appearance of your home and property. All investments need to be looked after and your pool is no exception. Homeowners renovate and maintain their home, they also service their car regularly, yet all too often their swimming pool looks neglected and unattractive.

Whether you are wanting to re-line your swimming pool (fibreglass or marbelite), fix leaks or repaint your pool, give HTH® Pool Assist a call to find out the details of your local National Spa & Pool Institute (NSPI), who will be able to recommend a reputable person in your area.

Marbeliting
A well maintained and operated marbelite pool should give many years of relatively maintenance-free service. Staining and decolouration of the lining may very well be because the pool has not been well looked after.

Fibreglass Linings
These linings are not guaranteed against staining or discolouration because this is dependant on proper care of the swimming pool.

Leaks
Leaks in a swimming pool can be difficult to detect. This means that good, systematic, investigative work is the most important key to locating troublesome leaks, and may even help reduce repair expenses. In many cases, identifying the leak location is a process of elimination - checking things one at a time. Once located, the repair of a leak is not as difficult as you may think.

Painting your pool
Painting of swimming pools is only recommended if persistent black algae has never been a problem. Unless the algae is really destroyed, being a mould growth, the algae will grow between the plaster surface and the paint, causing the paint to blister and peel.

YOUR FIRST POOL
Congratulations. Your dream of having your own pool has finally come true. You can cool off after soaking up the sun, have fun with the family, and enjoy a whole new world of entertaining. But you may be feeling a little unsure about pool care. After all, some people talk like this is rocket science. The truth is that pool care is basically simple, so to make sure your pool is always a pleasure, begin with the basics.

Pool Treatments
Pool water needs a sanitizer to keep it free of algae and bacteria. South Africa's first choice pool sanitizer is granular HTH® Classic Chlorine. You'll also find many pool owners using products like the HTH® I.Q.™ Floating Pool Control, or HTH® Lifestyle Liquid. (More about these on the HTH® Product Range page.)

Using a Test Kit
Test your pool water regularly. Maintaining a pool without testing is like driving a car with your eyes closed. Among other things, testing gives you the two most important measures of a healthy, sparkling pool - levels of chlorine and pH. You can use a test kit or Quick Test® Strips. (For new or problem pools, you may need the support of an HTH® Pool Assist Test Station.)

Maintaining the right pH level
Heard of pH balanced shampoo and pH balanced soap? Well, you have to have a pH-balanced pool - in other words a pool that is not to acidic, or too alkaline. When you test the pH level in your pool, you get a number on the pH scale. 7 is neutral, above 7 is alkaline and below 7 is acidic. Maintain between 7.2 - 7.6 for marbelite pools and 7.0 - 7.2 for fibreglass pools.

Maintaining the right Total Alkalinity
Relax. This is the last strange term you have to deal with for now. Your pool's Total Alkalinity should be maintained at between 80 - 120 parts per million. (ppm.) The right level of Total Alkalinity keeps your pool from changing pH too rapidly or too much.

Calculating your pool size
To tell how much of a particular pool chemical your pool requires, you need an approximation of how many litres of water it holds. Most pool products indicate dosages based the average South African pool volume of 50 000 litres. Go to the page on calculating pool size in case you need to adjust dosages up or down for your pool.

STARTING-UP/REFILLING
Whether you're starting up a brand new pool, or simply refilling an existing one - here's some advice to help start your pool up for economical, easy maintenance and years of pleasure.

Start-up procedure - freshly filled pool municipal water
1. Put the garden hose with a cloth tied over the end of it, into the deep end of the pool. Switch the hose on and fill the pool until the water level reaches the middle of the entrance to the weir. The colour of the pool water will be greenish - this is normal. The following steps will give the water its clarity as well as its balance. 2. 3. 4. Check and correct the pH level (7.0 - 7.2 fibreglass and 7.2 - 7.6 marbelite). Most municipal water is alkaline and in most cases above 8.0. That evening, add 2 cups of granular HTH® Classic for every 10 000 litres of pool water. Pre-dissolve the granular HTH® Classic in a bucket of pool water as this will prevent bleaching. Filter continuously for 24 hours. After 12 hours test the pH and correct if necessary. At this stage the automatic pool cleaner may be connected unless it is a new marbelite pool in which case you need to wait 28 days before connecting the automatic pool cleaner. Continue filtering until the 24-hour cycle is completed. 5. 6. Check the Total Alkalinity and adjust between 80 - 120 ppm. Only freshly filled pool water contains a low calcium hardness, which must be increased to prevent premature deterioration of the pool shell and equipment. Scatter calcium chloride over the pool water while the filter is running. Ensure that the pH is correct before adding the chemical. 7. Continue with normal filtration and chlorination.

Start-up procedure - freshly filled pool borehole water
We do not recommend the use of borehole water in swimming pools (refilling or topping up) as in most cases the water contains dissolved metals such as iron, which can colour the water or stain the pool. But where a borehole is the only source of water follow this procedure: 8. 9. Tie a cloth over the end of the garden hose. Place the garden hose into the deep end of the pool and turn on. When there is a depth of approximately 1 metre of water in the deep end, dilute 1 litre of HTH® Iron & Metal Remover in 10 litres of water and distribute over the surface of the water. This will reduce the possibility of staining. Continue adding water until the water level has reached the midway mark of the entrance of the weir. 10. Switch the filter to Bypass/Circulate/Re-circulate and circulate the water for 8 hours. 11. Turn back to the filter position, check the pH and adjust to 7.2. 12. That evening, with the motor still running, add 2 cups of granular HTH® Classic for every 10 000 litres of pool water. (See Calculating Pool Capacity.) Dissolve the granular HTH® Classic 2 cups at a time in a 10 litre bucket of pool water and add around the pool. 13. Filter continuously for 24 hours. After 12 hours check and correct the pH level (7.0 - 7.2 fibreglass pool and 7.2 - 7.6 marbelite pool). At this stage the automatic pool cleaner may be connected unless it is a new marbelite pool in which case you need to wait 28 days before connecting the automatic pool cleaner. Continue filtering until the 24 hours cycle is completed. 14. Check the Total Alkalinity and adjust between 80 - 120 ppm. 15. Freshly filled pool water contains a low calcium hardness, which must be increased to prevent premature deterioration of the pool shell and equipment. Scatter calcium chloride over the pool water while the pump and motor are operating. Ensure that the pH is correct before adding the chemical. 16. Continue with normal filtration and chlorination. 5 of 5
