One could lower the pH with a chemical you add, like pH Up, pH Down, Bullseye 7.0 (they make this in several different pH values, like 8.2, 5.8, etc.). But you probably shouldn't, as this will make the pH fluctuate too fast, and this can stress your fish and make them sick. Your pH should be fine. A stable pH is (within limits, you wouldn't keep, say, mollies in a pH of 4...) more important than the pH itself. My pH is 8.0, my tap water is 7.8 out of the tap
Well done Emma! Unless your fish are wild caught or the ph in the tank they came from is significantly different from yours, the ph should be fine. You can usually take a little more time in acclimating them by floating the bag, and then adding tank water to the bag every 15 or 30 minutes for a few hours to help them adjust.
I wasn't sure about the PH! This is great. I guess the test that I have said it should be around 7 so I just assumed I had to get it there. I guess I will just leave it alone and not mess with it, is this the best thing to do?
btw what type of fish do you have? certain fish like different ph's so 7.6 could be ideal... I wouldnt alter it even if you had fish that preferred lower pH like tetras and such but just out of curiosity what is in the tank?
7.6 is better than a lot of people's tap water (including mine ). Don't mess with it, chemicals are probably more harmful to fish than a slightly less than ideal pH. Remember that the fish store has the same water as you do, so the fish are already acclimated somewhat. In my opinion, pH is not really all that important.
