I have a 20 gal tank i am setting up as a refugium for my 40 gal reef tank. I planned on using my Fluval 304 as a return pump(since I already have it). Will this work? Can I use regular play sand for the DSB in the refugium (since I picked up the wrong brand)? I will seed it with live sand from main tank. Any input on what will work best is greatly appreciated.
