I recently moved my above ground pool. I filled the pool with pond water that cleared in a surprisingly fast 24 hour period. I added CYA and waited for it to show up on my test, which it did.
Seven days ago my CYA tested at 30. I use the pool math app, but I must have forgotten to enter the test results. I noticed on Monday last week, my chlorine use was increasing. I was having a rough time getting a proper SLAM done because of time limitations. I figured I was just fighting something unknown. My water is clear and sparkling...I just can't hold chlorine. I had a trip planned for Tuesday to Friday. I knew my pool wouldn't hold chlorine so I added algaecide: Kemtek 60% Algaecide Conc. active ingredient: Poly (oxyethlene (dimeythyliminio) ethylene (dimethyliminio) ethylene dichloride). When I came back, I tried in ernest to complete a SLAM, but I was running out of chlorine and test reagent.
I tested CYA this afternoon and it was 0. I added 4lb. 11 oz to knee high panty hose and hung them by a return.
Is it normal for CYA to disappeared like that? Did the algaecide do it?
Any ideas?
