The fundamentals of pool maintenance are the same the world over. The following guidelines are relevant to our clients in Bulgaria and all of Eastern Europe. |
WATER CHEMISTRY Water balance and maintaining correct PH and Chlorine residuals.
FILTRATION Back washing regularly and keeping sand clean.
CIRCULATION Ensuring that the system runs sufficiently and that there are no leaks in the system that may affect suction or pump operation. |
 |
Correct Level when doing a test are:
STABILIZER - 70 to 90ppm
FREE CHLORINE - 2 to 3ppm
TOTAL CHLORINE - always the same as FREE CHLORINE
PH (ACID) - 7.4 to 7.6ppm
TOTAL ALKALINITY - 80 to 120ppm
CALCIUM - 250ppm |
|
The red tests you can test at home, the others should only be tested in pool shops. We recommend that you take a sample to a pool shop once a month in summer to be tested. |
 |
Chlorine Test when testing chlorine and the reading is low e.g. Less than 2ppm, you need to add chlorine (hth) or turn up the chlorinator to a higher setting.
PH Testing when testing and the reading is below 7.4 e.g. 6.8ppm you need to add Sodium Bicarbonate or better see a pool shop specialist. When testing and the readings are above 7.8ppm you need to add acid (Hydrochloric acid). Add in doses of 500ml at a time; always dilute acid with 5 litres of water before adding. Test again after 6 hours and repeat if necessary. |
|
For chlorinators, salt testing is also done about twice a year. |
 |
Once a week you need to do a Backwash and a Rinse. When turning the selector valve (multi-port-valve) always turn clock ways and make sure the motor is turned off. First empty the pool weir basket and the pump-weir basket of all collected debris. Then do a backwash for approx. 2 min (or until sight glass is clear). Then turn handle to rinse for approx. 30 sec or until sight glass is clear.
Sand needs to be replaced every 2-3 years depending on the surround of the pool. |
The system is sized and designed to circulate all the water in the pool once every 12 hours, therefore you need to run the system 12 hours per day.
Should air bubbles appear at the aimflo (where the water blows back into the pool) you should contact your local pool shop for advice, as this means that the system is not pumping to its full potential and may cause circulation problems resulting in dull and ever green water.
