Back Yard Rocks

[usafitz]

Hey everyone! I'm new here, so just wanted to say thank you off the bat.

I've had my 135 Gallon aquarium up for about 3 months now and it's doing great. I live in the SouthWest and found some awesome rocks. I was curious if anyone had any information on how to test these to see if they're okay in my tank. All of them are smooth like river rocks.

I put them in a holding tank for a few days to see what it did to the water. Ph was a little high (7) but amonia, nitrate, and nitrite was at zero.

what would you do? :)

Welcome to Simply Discus usafits....
You can try a drop of muriatic acid to see if it reacts or fizzes which I would not use.
