I have a 23,000 gal vinyl liner pool, opened it 9 days ago and there is a brownish yellow stain only on deep end sides , below water level that cannot be brushed off. I had my water tested yesterday as follows:
pH 6.8 which is now 7.2 due o borax
TA 50 which is now 80
Calcium Hardness 100, bought stuff yesterday but reading your forum info should not worry about it in a vinyl liner pool, correct? Should I return it I have not used any?
Phosphates forgot to test, reading forum info does not matter in a vinyl liner pool correct?
I do have a heater hooked up to the pool that's not bypassed, incorrect calcium and phosphates do not effect the piping in the heater, correct?
I rubbed an orange on the stains did not touch it. So it's not metal, copper or iron stains any suggestions? I have never had or seen it before. I did add a bottle day 5 of opening of conquest sparkle, which I use every year for stains on the fiberglass steps and love seat, did not touch the liner side stains.
I do use chlorine tabs in a chlorinater , borax and bakin soda as needed. I have had high levels of Chlorine since the pool was opened, chlorinator is off right now.
Please let me know any suggestions on the stains, I am at a loss. They tried to sell me $50 stain remover but my chlorine needs to be down to 1 and I wanted to do the orange thing for metals before I bought it. That might be my only solution right now unless your have suggestion?
