I have a very cloudy pool that I can't fix. Just got my test kit in the mail today and my results are as follows.
pH - 7.5
FC - 20
CC - 2
TA - 360
CH - 400
I have had my pool since 2008 using SWG relatively trouble free and never required alot of testing/maint. Last fall a disaster with heat pump required drainage of entire pool and replacement of water. I closed the pool shortly after that and opened this spring to crystal clear water with a few worms in the bottom. pH was a little high so I corrected with muriatic acid and added what I calculated would be enough CYA to get to around 80 ppm. pH came down nicely kids swam and unfortunately turned off SWG for a week unknown to me. Opened cover to find white cloudy water. Figured it was chlorine deficiency and began to shock very aggressively in the hopes to clear it as my eldest had a pool party scheduled in 3 days. No success. Still cloudy with high chlorine. I had to cancel the party.
I have decided to finally work from a position of knowledge. I ordered the TFT TF100 test kit and joined this forum. The results are as above and I don't know where to start. Common sense would tell me that large amounts of CYA would help both with the CYA and TA levels. Common sense has failed me regularly however and I am pretty sure I am wrong again. Frankly don't trust the results that our local pool store (30 minutes away) have given me before. I have no idea about the calcium.
