Have your sample checked but I doubt you have chlorine lock. I think at this stage your stabiliser level is lower than it should be.

pH/TA

by flyfisher » Sat 03 Feb, 2007 23:29

First post

I am having trouble balancing pH and Total Alk. My TA is about 120-130 and pH is 6.8. Should I concentrate more on lowering TA or raising pH?

Last post

I would be inclined to lower the TA. If you aerate the water you will find the pH will rise.
