My name is Bryan Barnard and I live in Nashville, Tn. I have been lurking around on this site for some time now, usually when I am having a problem with my pool, and I finally decided to sign up on the forum. I have a basic 18x40 rectangular shaped pool with a liner. Last summer I converted it over to a SWCG system and I also upgraded the pump to a variable speed Hayward pump.

My question is this: Since converting over to a SWCG system I continually have to monitor the ph levels because they always tend to go over 8. I normally use the ph lowering regent from Leslie's pools but over the weekend I decided to try using muriatic acid. Since this is my first time using muriatic acid is there any ratio that I need to keep in mind so that I do not lower the ph too much?

Thanks,
Bryan
