First let me say that I am very new to salt water tanks. I am planning on getting a 180gal tank and having it drilled so that it will be somewhat reef ready, I read somewhere on this forum that as water flow I need at least 15 to 20 times the tank, is this true. I also want to know a couple of things. 1. how much live rock and live sand do I need. 2. how big does my sump and fuge have to be.
:notsure: :help:
