Am I crazy to consider adding CYA while still using Trichlor pucks? I've been using the pucks (in addition to bleach) for about 5 weeks now and all of the CYA tests I've done (TF Kit and strips) have indicated I have little to no CYA. I thought after 5 weeks of using the pucks in my feeder my CYA levels should have risen. Knowing that the only way to get rid of excess CYA is to drain water, I really don't want to find myself in that situation. As soon as I get my CYA levels up using the pucks, I planned on not using them anymore and strictly sticking with bleach. But I'm afraid that I could be wasting bleach by not having sufficient amounts of CYA. My FC seems to stay steady so perhaps it's not an issue? Any thoughts?
Here are the readings from last night:
FC = 4
CC = 0
TA = 100
CH = 120 (this I need to get up - I have a gunite pool)
PH = 7.2
CYA = ~10 or less?? (on the test with all the solution in the tube I can clearly see the black dot)
So, should I break down and add CYA?
Thanks in advance!
