You can add some crushed coral to your substrate (or filter) to raise the ph. You can also use limestone. Be aware that this will also raise your gh and kh (which should be fine). I've also heard of people using baking powder, but I'd avoid that as you'll have to keep adding it and it won't be as stable as the first two.

How low is your pH? Most fish are just fine with a range of pH.

Thanks for the advise. Now that you mention it, I do remember reading something about the coral raising pH; I'll look into that.

Right now I'm not 100% sure on what my pH is from the tap. The test strips that I have only go down to 6.4, so I know it's under that; probably around 5.5-6. I'm planning on making a run to the LFS on Thursday so I'll get a better test kit.

Thanks for the help.

That is pretty low. What is the pH of your tap water?

I am not sure I would mess with it using anyhting but crushed coral or limestone but they are not going to bring it up very much.

Is there possibly something in your tank that is bringing it down or is it more likely just your tap water? If there is anything "odd" that you have in there let us know.

Test strips can be pretty inaccurate as well- I'd recommend using the API master liquid test kit. You'll be very glad you've got it in the long run and you'll be able to get a much more accurate reading of your ph (although you may want to also buy a separate low-range pH test). Luckily it's much easier to raise ph and than to lower it in a natural, stable way!

wow! thats low PH, good for breeding fishes like tetras. Good for you, our water here would have 7 or 8..
My CO2 injections makes it acidic (lower).
