I am using the Rapids pro wet and dry filter. Its great. I think it rated at 700 gallons per hour. It comes with a over flow box and a built in Protein Skimmer. They have a new one out with a better skimmer. I dont use the bio balls that came with it but you can fill it with whatever media you want. It is a great way to go I think. To me the only better option would be a Refugium.
700 gallons w/ a protein Skimmer vs 159 gallons That was enough for me to get it. Google it. Its great trust me.
