I have read pool school and would love some clarification of a couple of things. I started this season with zero CYA and added approximately 3-4 pounds via sock over a three week period. Tested with my Taylor kit a couple weeks ago and it was less than 30. Tested today (as I am noticing algae in the pool) and it was 80. I have been using both liquid 12.5% chlorine and the pucks via a floating dispenser. I understand that now that my CYA levels are so high I would need a much higher FC level and that is why I am getting algae. My questions are:
1. How, exactly, do I lower the CYA levels? I understand I will need to drain some water, but what is he best procedure for doing this?
2. Should I just stop using the pucks altogether once I get the CYA levels where they should be (would that be around 30?)? Just add liquid bleach and stabilizer as necessary?
3. I have added 90oz of liquid 12.5 bleach this morning and am brushing off the algae from the liner. What should I do next? Start draining a couple feet of water and re adding?

CYA. 80. Using my Taylor test kit
Thanks for your help on resolving this ASAP. I was hoping I wouldn't add too much CYA, and it appears I managed to do just that. Sigh
