    Unhappy PH in tank is dropping

    I checked PH levels 2 weeks ago and everything was good at 8.3, last week I checked and it was at 8.2. Now I check and it is about 7.8 to 7.9! How would I bring up the PH to proper levels without killing all my livestock??? Also would a low PH make a leather not extend?

    Need More information to help understand what's happening. How long has the tank been setup? What are the other water parameter numbers? What is the tank stocked with? etc

    The tank has been up and running for about a month and a half. I have a lot of corals (LPS,Softies) and all other parameters are good.Amonia is 0. Nitrate and Nitrite is 0. I also am running the skimmer when I do a test.

    your running the skimmer 24/7 I hope. the skimmer has an effect on ph [good] by oxygenating the water. I'm no chemist but REEFMUTT could chime in more clearly.
    also, ph will sometimes fluctuate. are you using any additives or doing regular water changes?

    I have been using additives like calcium and alkilinity. I have not been using any PH stuff though. Yes the skimmer is on 24/7. I went by Marinescape yesterday and I saw that they had some stuff to bring PH up. Is that good for the tank?

    No it's a band-aid.

    If your pH is dropping there's usually a problem that needs to be solved.

    Likely it's largely due to your tank only being 6 weeks old. That's a very young tank & your bio filter likely isn't completely established.

    Still I'd check for a dirty sponge, clean out the protien skimmer, and consider doing a partial before I'd add any chemicals.

    Are you testing your Ca & Alk levels before dosing btw? You shouldn't dose anything unless you know how much

    Cheers!
    There is nothing so permanent as a temporary measure.
