Hi. We are new pool owners and were surviving ok until now. I am currently very concerned about our water situation!
We have an 18x36 vinyl IG- 28,000 gallons- Hayward S200 sand filter (installed 3 years ago, but I don't know the flow rate or pump size) we live in Ohio.
Our real problems started after the week or so of rains. I have not been holding a good chlorine reading really all summer, but after the rains my water became very cloudy. I went through every cloudy remedy 1 by 1- muriatic acid, borax, shock (4 1b bags)- and not one of them helped. Backwashed the filter, and nothing. Worried, I went to the pool store with my water sample on 7/28:
He also tested for phosphates, which was positive for VERY high levels. I treated the pool with the phosphate remover, then used the clarifier 24 hours later and my water looked worse! I shocked with 5 1 lb bags and waited another 24 hours to go in again. Water results on 7/30:
We retested for phosphates- levels were still VERY high, a little lower than before, but not significantly enough. I treated again for phosphates and also used a copper based algaecide. Waited 24 hours and shocked the pool again- 4 1lb bags of shock. All along I have been testing my water with test strips and the OTO and Ph drops. My PH seems balanced between 7.2-7.6 over these last 2 days. My TC level has been virtually non existent until I shocked again. The filter has been running 24/7 for 5 days now. I have tried muriatic acid again, the water is still very milky like cloudy- muriatic acid always cleared up the water before. I have seen some algae in the skimmer even after the algaecide. I am just at a total loss at this point.
Oh- and somewhere along in here I have also used metal control, we are on a well. And about 10 days ago I added stabilizer because I never got a reading on that on the strips. The water is milky with a greenish/blue tint in the sunlight.
I would really love to be doing this but unfortunately am really doing this !
I really appreciate any help on this...
Thank you so much!!
