Just moved back into my house in Pflugerville (north of Austin) and the pool had been allowed to go greenish black and was full of leaves. (renters... UGH!) My son and I brought it back to sparkling with chlorine tabs and lots of backwashing. However, it's begun to go greenish the last few days. Taking the water to Leslie's we learned that the CYA is too high to be remedied. So, we are draining 3/4 of the pool according to their instructions. Also taking apart the pump and soaking the fins, then using Zeo Fiber instead of DE once the pool is refilled. I had a pool service before this when we first bought the house but I don't now, so I must learn the BBB method and how to maintain this thing. My questions are as follows:
1. Is Zeo Fiber better than D.E. and if so, why?
2. Suggestions on a test kit I can get today that will suffice until I can order online?
3. Once the pool is filled the guy from Leslie's said we would probably "be good" for at least a year or two. Surely he didn't mean adding no chemicals at all?
4. Did I end up with these outrageously high CYA levels because of the chlorine pucks?
My pool is a 22,000 gallon gunite, I believe. Any help getting up to speed quickly is greatly appreciated.
