Get your TA down, it will also help with the pH stability and when you adjust pH don't lower it below 7.6 to keep it from rising too fast. The lower the pH the faster it will rise.
OK. So up to 80 CYA is best but I can get away with lower FC due to the fact that the SWG is able to maintain a steady supply (while on of course) of chlorine? Just trying to understand the differences from SWG and other methods of sanitation.

Next, Should I adjust the TA first and then PH or vice-versa?
