yesterday i've added about 30lbs of gravel in my bare bottom tank. shortly after, i noticed my FH scratching/flashing continuosly. i did a PH test and it seemed to be higher.
so my question is, did the gravel raise the PH? i was under the impression that gravel does nothing to the water chemistry. and should i remove the gravel?
