New frag tank setup 8g

if you want to keep it a frag tank i'd say leave the sand out, you want good flow and clean water in a frag tank. this shallow tank would probably cause the sand to blow around and just trap detritus. granted, if you want to keep it aesthetically pleasing get some sand, but not much IMO.

Very good point their. I am going to put gravel mixed with sand so it won't move around much but just a small layer just to cover the bottom. Thanks for the heads up @TheKleinReef
