Hi all. We are new pool owners. We have a Simple Salt pool. Things started out great after opening the pool up this season. The water felt wonderful and smooth. Then summer hit with what is going to go down as the warmest month on record in Buffalo, NY. I have not had a clear pool since mid June. A constant battle of keeping the pool from turning really green or just a bluish green. I learned about Alkalinity and Ph. Finally, though adding dry acid (sounded scary to me) we were able to get those levels down into normal range. I just received my test kit and tested everything. I realize my free chlorine is quite low (less than 0.5 ppm) and my CYA is less than 20. Any suggestions are welcome. Would be nice to see the bottom of our pool again!
