Ok, I have been trying to do as much reading as I can and move forward, but still have a few questions:

Readings;
FC 5
CC .2
Ph 7.4
TA 210ish (I have already added nearly 1 gallon of muriatic acid in the last 24 hours)
CYA 0
I got some of the powdered CYA and added to the skimmer today, 1lb as of right now. From what I understand I need to get the CYA up, currently I am flying through the liquid chlorine. Losing alot during the day. What is the quickest way to increase the CYA? Also, my ph jumps up pretty easily, which I think is due to the alkilinity. Once I add the muriatic acid, how long do I have to wait to add chlorine?
