what do you guys think of putting sandstone rocks in the tank? I currently have and for many years used regular rocks from the creekbed, just wondering about sandstone rubbing off and affecting water quality. thanks for your help

I've never used sandstone in any of my tanks, so can't give my personal opinion on this, but I found this online:
"Sandstone is made of sand grains cemented together and it's mostly safe stuff. The cementing material in some sandstone is calcite, which again isn't particularly good for an aquarium unless you actually want your hardness and alkalinity drifting upwards. You might want to give it the acid test; a sandstone cemented with calcite will fizz under a drop of strong acid."
