Welcome to our forum.
What's the best formula for adding baking soda -- say if your ph is 7.0 in a 400 gallon tub, how much bs should be added?
Be sure to allow things to settle down for several hours before retesting. Sodium Bicarbonate or Sdium Bisulfate will cause a drastic swing in pH and TA which will even out in about three or four hours. If I am double checking, I usually test the following day. 8-)
Heck it takes me 3-5 OZs. of Baking soda per water change to raise it from 6.8-7.0 and maintain it during 3-4 months.
sounds like everyone is familiar with baking soda then. thank you for all the input. i have to get this thread printed out!
I still buy and use pH UP ([glow]Sodium Carbonate [/glow]I believe) for when my TA is OK.
