Thanks for all the help this summer. Pool is looking good. However I am getting frustrated with all the bleach I have been putting into the pool. I have been shocking for the last 3 years with ChlorBright per my local pool store. I wish I would have found your forum much sooner so my CYA was not so high. I have been following your charts and calculators but can't keep up with the FC.
Here is what I found with the TF-100 kit (Vinyl 22,000 gal):
CYA: 110 (pool store said 40)
Temp: 90 (Atlanta has been around 100 degrees for several weeks now)
Any suggestions to lower the CYA which I believe would help reduce the quantity of bleach that I have to add?
