Ordered the test kit- here's the results recorded about 10 minutes ago.
CYA 100+ guess- 120
Pool data- will update my signature shortly. ~35,000 gallon gunite pool w/ attached spa, 2HP pump, DE filter
My polaris has been removed from the pool because I found that the combination of the booster pump with the primary pump was drawing too much electricity and the electrical wires were getting hot. The pool equipment will be rewired and the polaris hooked back up soon.
I've read enough that I assume the recommendation would be to drain/replace water to lower CYA. Here's the rub- the pool is going to be completely drained and remodeled this fall. My preference would be to deal with the high CYA for the summer, although I'm not sure what I can/should do. Pool service (I know... I travel for work) wants to add phosphate remover, and I've read info here about phosphate remover.
I'm using chlorine tabs for now and I anticipate continuing through the summer. When we redo the pool equipment I'll add a stenner pump for liquid chlorine.
