Hi everyone, it is another new pool season, yeah!! I have had my pool open since the end of May, and have had very few problems. I feel I have to retrain myself each year, smile! We have a 25,000 gallon, I think? inground vinyl pool that is 20 by 40. I just Now found my test kit, that was safely hidden from me in the house. So this is the first I tested it myself and took total control. My readings are: FC: 4.0, CC: 0.5, PH- 7.4-7.5, alkalinity- 60, CA 50, Calcium Hardness 60. I am thinking for one thing I need to put more stabilizer or clearifier ( they are the same, right?), in, that it needs to be higher? Also I don't see where you pay dues to belong, did they change the forum rules? thanks so much!!
