Gavin Posted March 11, 2010 Report Share Posted March 11, 2010 I have a fountain type jets that shoot up and down into the pool that I'm using to raise the pH. I dropped TA down to 80 and pH went down as well to 7.0 so that's why I'm aerating. how long will it take to raise pH to at least 7.2? Thanks. I was thinking about leaving system on for 4 hours tonight to try and raise pH to 7.2 Quote Link to comment Share on other sites More sharing options...
