Isn't colorquartz basically a sand? How will maintenance of that differ from sand?. I HATE sand so much now. I am finally in the process of changing it out now to colorquartz.
I'm trying to decide on a substrate for my low light tank...I think I'm going with Turface pro grey with a white sand river...should this be a relatively low maintenance substrate? I'll use some river rock scattered along the rivers edge to help keep the two substrates from mixing too much (though I don't mind a bit of blending). Thoughts?
