cl - 10+
fr cl 10+
ph ~7.2
tot alk 120
Cyanuric acid 100
At 6 pm The Cl and Fr CL go to zero and other levels stay the same. So I add shock and the levels go up. This process has been the same for about 5 days. Any thoughts?
I use 3" tabs in my chlorinator (5 tablets) and I run filter for 8 hours. The setting on the Chlorinator is maxed out. Last year, I think I used 3 tablets and ran filter for 4 hours and that was fine. Bottom line, something is eating my chlorine. Any help would be great. Thanks.
I am going to make a guess that you are constantly fighting a nascent algae bloom because of your high CYA and that is what is consuming your chlorine. also, how are testing because there is NO reliable way to test for high C>Ya levels and there is a very good chance your CYA is actually higher than 100 ppm. The fact that you continue to use trichlor means that your CYA is continuing to climb since trichlor adds 6 ppm CYA for every 10 ppm FC it adds.
