pH rising

    My pH keeps rising in my 15 gallon tank it's at about 8. Ammonia, Nitrite and Nitrate are at perfect levels but I don't know what is going on with the pH. I have 4 Juvenile Angelfish in this tank and I read they aren't good with pH changing drastically. I added 15ml of pH decreaser on March 5th. Tested the tank last night and no change in the pH. Is there anything else I can try without adding more chemicals to my tank? I've read that distilling water will help lower the pH. Does any have any experience with that?

    Have you tested your tap?? Maybe something changed from that, making it more alkaline...

    Good afternoon,

    I would recommend that you not use chemicals to alter your pH levels. They are unstable and can lead to a pH crash resulting in fish loss. Sudden changes in pH can be fatal to your fish. It is more important and easier to maintain a pH level than it is to try and pinpoint a certain level and keep it there via frequent water changes.

    Most fish for the home aquarium can adapt to the pH levels we have right from the tap with chlorine/chlorimines removed first. :)

    Here is a link on pH that will give you natural methods of altering your pH which will much safer for your fish:

    A pH level of 8.0 shouldn't be an issue for your fish as long as they are acclimated properly. I suggest the drip acclimation method for all new fish:

    Quarantine for new fish is highly recommend. I recommend for 1 month.
