i had to lower my TA several weeks ago do to switching to swg system. I aerated for about a week and had plenty of splashing going on. now over 2 weeks later since I got TA right I cant get ph to go higher than 7.2. Im not having any issues at all, but I thought you needed to keep it at around 7.5. Why cant I get it to come up?'
