Well, last week when I tested I discovered I had 0 CYA. I stopped tending my pool in October when my mother became ill and passed away, so there has been plenty of algae building up. I was out of CYA so I just put in 3 jugs of bleach until I could get more supplies. I was wondering if I had ammonia so I bought a test kit for that today and it reads positive 1.0 ppm. Yay.
My question is, do I attempt to add CYA first or do I shock to get rid of the ammonia then add the CYA?
For those trying to crack the CYA conversion mystery, the weather over the winter was mild, with only 1 light freeze, and several warm days in the 70s.
