Help! Crazy CYA

[aceman]

I hope to get my kit in next week. I've stop using pucks and starting on BBB. Sounds like my only option is to drain 1/2 the pool. The pool store try to sell me CYA removal. Anyone heard of such? Expensive though, $45/gal. to remove 50ppm/10,000 gal. Anyway with my CYA over 200 is it safe to keep the FC that high. The water is clear with a hint of green tint.

CYA remover has been discussed previously on the forum several times. Apparently it turns your pool milky white just as the solution in the cya test does and then your filter attempts to filter it out. The consensus around here is not to use it.

You're going to have to keep the Cl that high to finish clearing up the green, but I wouldn't really be comfortable swimming in it on an ongoing basis. I really thing partial drain/refill is your answer. But then, it's not my water bill..........

Great day. Got my kit in today and here are my first results. Way different from the pool store readings.

I would start aerating the pool (turn the return jets to the surface - turn on a fountain - have kids jump in). This will lower your ALK and raise the PH. Otherwise, you need to add Borax to get your PH up.

You may also want to still consider a partial drain and refill as your CYA is still really high.
