im goin to take the pot out and put it in the 14 gallon,then ill do a water change and the next day ill check ph in both tanks again, i think it may be the pot affecting the ph
So you think the pot is lowering the pH? Please let us know what you find out. I'm curious to see your results!
I would have expected it to either not affect pH at all, or to raise it *if* the pot contained an additive like lime or chalk. Not sure what could be in there that would *lower* the pH though. Hm, I'm going to search the internet to see what I can find out.... (So much other work that needs to get done, and yet I just want to look at fish-related things. LOL)
