Hi, i'm a totally newbie here, so any advice would be much appreciated. I have one 10 and one 29 gallon tank, both freshwater, both with fake plants and driftwood. I had my water tested today at the lfs ... the ph in both my tanks is different, and both are low. The ph in my tapwater is about 6.2 ... the tanks were only a little better than that. Any advice for bringing the ph back up? all other readings were ok except .25 ammonia, which i'm dealing with using Prime by seachem. Water is at 80-81 in both tanks.
