This july the stinking pool store had me add a stocking full of CYA. The problem is that my level was 67. Now I'm trying to clear my pool from a CYA of 200ish. The pool store and even the three other pool stores I went to all told me this was an ok level, and with a little persistence I could clear my pool from a stubborn alge bloom. Buy this alegcide, we'll worry about the copper later... Dump in 20 gallons of bleach at a time...
I was sure the problem was not just a stubborn algee, so after reading your TFP school... I am making the switch. My taylor test kit arrived this week and I'm refilling my pool from a partial drain. I don't think it will be enough to get the CYA in check, but I plan on closing the pool in a couple weeks, and I was hoping to use it before the season is over.
I'm frustrated and mad a the lack of ownership from the store, but I guess if I finally learn how to really care for my own pool, I'll be better off.
Thats my story... Wish me luck!
