Ph balance is higher than I want in my 30gal fish tank. What to do?

jkohli89 asked:

I have a 30gal fish tank with 4 black tetras, 1 mollie, 2 pleco, and a couple snails. The ammonia, nitrite, and nitrate levels are great. No problems. When I test the Ph balance tho, it is around 7.6. This value is a little high and I was wondering HOW do I get it down and KEEP it down?

    You can buy chemicals that will buffer the pH down try API or Seachem.

    You can put a bag of aquarium peat in the filter to keep the pH down or bogwood will help too

    For what you’re keeping it’s fine. A stable pH is almost always better than one you must add chemicals to maintain.

    Driftwood in the tank will lower it a bit as well as peat moss but each time you do a water change you’re changing the pH causing stress on the fish.

    That ph is perfect for the fish you have, and I would strongly suggest you leave it alone. Ph in the range of 6.0-8.0 is generally considered fine for most fish we buy from the store, since most of those fish are tank bred or farm raised. The only exception would be wild caught fish, and they’d require the tank to be set up pretty much exactly how it is in the wild where they come from.

    When you get into altering ph, there’s a lot involved, much more then just putting a ph up/down chemical in. You have to know what you’re doing, and alter the gh and kh to get the ph to stay stable. A stable ph is much better for fish then one that fluctuates, which commonly happens when you try to alter the ph.

    Again, your ph is fine for the fish you have.
