Hey guys/gals I have a 18' round above ground pool and was trying to put in a little bleach to bump up my chlorine level and as soon as I add the bleach it stains the bottom of my liner. I got some Stain Free added it and it lifted the stain,but as soon as I add the bleach it stains it and turns the bottom light brown. I use a liquid test kit and test every other day all my measurments are correct for my size pool FC,TC,TA,CYA,CA. I use tablets normally in skimmer and just use the Bleach to keep my Chlorine Level up if it falls after a heavy swim. The bleach I am buying is Dollar Store brand non scented regular bleach but it is (HE) does the (HE)affect this? So my question is why is the Bleach staining my liner as soon as I as I add it?
If I wanted to do the BBB method I could not cause the Bleach would stain my liner.
