I had a late opening for my 21' pool. Filled the new liner with hose water and much to my surprise, my 1 hp Hayward pump wasn't working so I orderer a new one over the internet. Seeing as it was 90 degrees and a few days before I could get one at a reasonable price, I put a bunch of triclor minitabs in 3 different socks and threw them into the pool to avoid the feared green plague. After a couple of days I noticed a white residue around the socks and thought it was CYA residue that would go away as it may take a week for CYA to dissolve into the pool water. Finally got my new pump after 3 days and I have white blotches an my liner floor! Now my query is, did the triclor?CYA tabs bleach my liner floor white? It doesn't seem to brush away. Did I mess up?
