Thanks everyone, for all the feedback. My GH KH test kit got lost in shipping, so I am waiting for a replacement. When I get it, I can test my tap water. Then, I will have a better idea what I need to do. It sounds like Equalibrium is the better of the shelf product.
Just got the box of Flourite, now to rinse. I have been testing rocks with muriatic acid. Most of our local, beautiful, river rock seems fine. Just because, I tested my old gravel from Petco, their econo grade. It contains a fair portion of light color material that bubbled away.
