The amount of live rock depends on your plans.. less for reef, more for fish only with live rock, or if you have a skimmer.

The rule of thumb is 1-1.5lbs per gallon. I have around 40lbs in my 33gal.

I would also get rid of the fluval & get a skimmer instead, unless you are only planning on running carbon.

A sump is a better idea if you can, I just upraded to a sump, and never will go back.
