I have an 18x33x4 above ground pool. I've been using a frogger for the past 6 years and everything has been fine until last year. My levels started getting out of wack and the water is eating up my solar cover and anything plastic. I spent a fortune with PH up last year and the pool store told me to just keep adding it. I gave up on that whole thing when I found this site and the BBB method. Here are my reading as of tonight:
CL= 5-6 I have an HTH test kit and the CL test also has the Bromine test. I know I need to get a better test kit but can't afford it right now.
I started putting in Borax per the pool calculator to raise the PH but the reading hasn't moved. Should I have added the baking soda first to adjust the TA and then use the Borax?
My liner is slightly stained. can I get rid of this once I get all of the numbers in line with some type of stain remover?
