Hm my reply didn't post. I'll try again.

Thanks for the advise on the rocks. That coulda been a costly, and big mistake. I'm timidly using PH UP currently. I'm cautious, not wanting a big PH jump all at once.

I have a 55 gallon bow front. It's running with a Rena SmartFilter and an extra little 10 gal spec filter just for extra water circulation.

I have fish already. Mostly livebearers and a mix of other peaceful community fish. Mix in a few inverts and frogs, plus a lot of live plants, and that's pretty much it.
