I've read that crushed coral can cause nitrate spikes, right? This is my first SW
tank, and I will use sand as a substrate, because I want to keep it fairly easy! But can I use a cup or so of CC
for the fridmani to play with?
Bizzybeas, what type of gravel do you have? I have some Estes brand gravel (beige-whitish) in my FW
tank. I could put a little of that in the SW
tank if the fridmani would like that. Or is this not a good idea? I want to do whatever will make the fish in my tank happy!
