I'm not sure if this has already been asked, if so, please let me know.
I'm interested in setting up a barebottom tank after a move to a new place for college. Is there a recommended size for a barebottom? I'll probably only have space for a 20-gal (at max).
Most of all, how do you set one up? Do you have to start with gravel and then work your way down? Can you do a fishless cycle for a barebottom, or is it too difficult for the biobugs to start that way?
If there is a best way to do it with the least gravel, please let me know. I don't really know what I'll do with the gravel once I'm done cycling it. It'd be such a waste.
