Hello. First let me say I'm NO pool guy by any stretch, up until 4 years ago when we purchased this house I had never had any experience with maintaining a pool. For the most part I have been able to maintain the pool by reading the post on this site and other sites on the internet. This spring/early summer has been very trying for me to get the pool swimmable, and with 2 teenagers wanting to spend there summer vacation in the pool it has also been pretty stressfu too..lol. My original issue was with a chemical in-balance and i just couldn't get the water to clear up... which brings me to yesterday when I finally broke down and went to the local pool/spa store and had them do a water sample. they confirmed that the pool was high in phosphate. so we purchased the phosfree they recommend. The lady at the store told us to poor the chemical in at the skimmer and not to touch the filter for 48 hours. well not much longer after I poured in the phosfree I lost suction from the skimmer. Now I have no suction at the skimmer but the pump is running fine and the pre pump basket is clean and the water is flowing good with no bubbles. Also the jets have all but stopped circulating water. When I first turn on the pump the jet closes to the pump bubbles some then it stops and it losses its circulation. The pool is 39x14 and it has a Hayward pump, a Hayward C1200 cartridge filter and a CL200 clorinator. The pool has one main drain at the deep end and 4 return jets. Im at my end with it...I build race cars..lol..I'm about a breath away from filling the dang thing and turning it into a base for a nice steel building to store cars, parts and tools...lol. Any help would be greatly appreciated not only by me but my kids..lol. I think they have lost faith in me fixing it..hahaha.
