PH Question
 

Hi I'm wondering what I should be be doing about this low Ph. I've got 1 koralia 3, 1 koralia 4, 1 Mp 10, and the 2 stock pumps that came in the RSM 250, so it's not lack of flow or gas ex. at the surface. I think it could be 1 fish to many? Any suggestions. Thanks.

Ph 7.4-7.7 on a salifert kit.

Check your nitrates. If they're high, then you've got too many fish. Two things are important for raising pH - aeration in your skimmer and lighting. The more of either, the higher the pH. Higher alkalinity will increase the lower limit of the pH swings.

I wouldn't worry about it too much. Mine is around 7.6 - 7.8 right now and I'm not worried, all my fish and coral are happy so thats all that really matters. There are lots of people out there who don't even test their pH.

there's a lot of good information in this recent pH thread..

The general consensus is that if all other parameters are in check and your tank inhabitants look like they are doing well then don't worry about your pH.

Test kits aren't very accurate, buy or borrow a PH meter. If your PH still reads 7.4 with a meter you should try to bring it up.

No3 is at 5. As I've previously posted I have a 5" Yellow head goby that I will trap and get rid of shortly, if someone wants him I would like to trade for corals.

I am vodka dosing, but I was interested to find out about the link from frozen food to excessive No3. I was aware of to a degree, but I almost exclusively feed frozen. I wonder what people prefer as alternatives aside from making their own because I'd rather not have to.
