Someone please please help me!! I have had my pool for 3 years. A 30ft round above ground. This is my second year of opening it and i cannot get clear water!! I had the same problem last year and dumped close to $800 in chemicals (all recommended by the pool store). This year i was determined to get clear water. I switched from a cartridge to a sand filter, installed a frog system, and most importantly had a helper. We vaccuumed ro waste, brushed, added chemicals such as shock, yellow x algae killer, ph up, alk down, floc, pool first aid, and blue magic clearer and still i have cloudy water with small white particles floating in it. It is blue, not green but still very cloudy. I leave my filter running 24 hrs/day. I backwash the sand often. I vaccuum and brush almost every day. My chlorine levels drop to nothing within a 24 hr period. I have chlorine tabs and have tried liquid bleach. What in the world am i doing wrong?? The pool store just says keep doing what im doing. But, something isnt working. Please help!!!!
