Here is my long story short! Last summer we put in a new liner, sand filter, and installed a SWG. Yeah! Our Hayward 1 1/2 hp pump died again in the fall. This was our 4th one in 9 years. We put in a 2hp this time hoping it would help problem. Thinking was our pumps are so far from the pool we needed more hp to keep it from working too hard. Fingers crossed! Anyway - that's why we lost our pretty water again!
We installed the new pump and cleaned out debris 2 weeks ago and started the shock process. The green went away in a few days leaving the water very cloudy. I know it takes time but I wanted to make sure I was on the right track. We brush the pool at least a couple of times a day. I have not done the overnight FC drop test yet. I am posting my numbers below. When we started 2 weeks ago, our CYA was 0. I have been trying to bring it up slowly. I would say it is almost a 20. My pH has been high i have added muratic acid, but I see I need to add more. We have the SWG turned all the way up thinking it will help keep the FC up. Thank you in advance for your advice.
