I only added lithium hypochlorite (dry shock....have a couple boxes of this powder shock lying around...so figured i could use it up over time as well). So no CYA was added at all. Have tested the CYA a couple times and it is stable...about 32-34....definitely much closer to 30 than 40.
May try adding again at some point and see if it recurs. Certainly odd.
whole thing literally lasted less than 3-4 minutes, and there has been no change in pool clarity at all. (and FC lvl went up as expected).
thanks

Hello all!
Great summer thanks to TFP!
Finally closing pool.
Have a quick question.
So, will be bringing my pool up to slam this weekend and closing a few days later.
I note in the pool closing post on here that it recommends adding polyquat algaecide for the winterization...and being in indiana where the temps can be mild, probably a good idea.
My pool company recommends using banish for the winter (copper-based algaecide).
any thoughts on this vs the polyquat products?? I have an abundance of either algae all 60 or backup 2 that i think are both polyquat products (since i am no longer using these for pool maintenance using the TFP system).
I was feeling a little hesitant to use the copper based product and have used polyquat in the past.
thanks!!!

Don't used the copper based stuff. The algae all 60 is what we call "polyquat" and is fine if you have enough. The msds on the back-up is unclear.
