alk & top off water


New member
i was wondering if anyone makes their top off water alk the same as the main tank. i've been adding baking soda to mine. making it at 10. the same as the main tank. didnt know if that was a bad thing or not to do.

I don't see a problem with it. I do this myself. I find that it maintains a stable alkalinity for my tank. I get less fluctuations in alk and pH.
