WHEN THE COVER WAS REMOVED FOR THE SPRING THE WATER LEVEL WAS LOW. WHAT COULD BE THE CAUSE?? -Before jumping to conclusions that the pool has a leak there are a few other things to take a look at. Check the cover for holes, even the smallest hole will allow the water to perk up from underneath. If a cover pump is used to remove rain water the pump will also be removing the pool water as well. If there is no hole in the cover, a lot of water displacement can happen. This occurs when rain water or snow weight becomes so great that it is pushing down on the cover, which then pushes the water from underneath up and out of the pool. This usually happens with big snow storms or if a cover pump is not used. LOW PRESSURE ON FILTER TANKS (this does not mean to backwash filter-common misconception) -In the spring the most common cause is a clogged impeller. This happens when debris or organic material that gets passed through the skimmer and pump baskets and gets lodged in the impellar. The impeller is a veined disc that draws the water through the pump and into the filtration system. When debris obstructs these veins less water passes through the filter resulting in lower pressure readings. Making sure that your pump basket isn't cracked can prevent this problem. HIGH PRESSURE ON FILTER TANKS -When the pressure on the filter tank goes up 8-10PSI then system needs to be backwashed. Remember after every backwash it is necessary to add more DE to the skimmer. Make sure you know the right amount; usually 6lbs. ARE SALT SYSTEMS REALLY CHLORINE FREE? -NO, the salt systems are producing a pure form of chlorine. The production of this pure chlorine does not have any of the additive that granular chlorine or chlorine tablet have, therefore making it easier on the eyes and skin. This process is created through electrolysis and repeated indefinitely as long as the proper salt level is maintained. CAN'T KEEP A CHLORINE LEVEL IN POOL -First make sure that the water chemistry is balanced including the cyranaric acid. Then ask for your water to be tested for phosphates. Phosphates are a nutrient for algae therefore chlorine cannot properly do its job to keep up with the high demand. Phosphates are a main ingredient in lawn fertilizer so be careful when doing lawn work this spring and summer.
