So i have recently purchased a 30 gal tank to use as a refugium on my 120 gal reef tank. I currently have a wet dry setup and would like to go refugium for the added chemical stability and for some free fish food. But as most are, I'm a little unsure on design to get the most bang for my buck. I would like to have most the aquarium serve as refugium and less area for pumps and such. Any help would be awesome! Also thanks for letting me into the forum!
