Ok well let me ask u this, keep in mind its a 55 Gallon FOWLR. Would two Hydor Koralia 2 Aquarium Powerhead UL 600 GPH be enough circulation for what i need and has anyone ever dealt with Aloha Aquariums before? They have these pumps way below what they go for at the lfs. http://www.aloha-aquariums.com/servlet/ ... a-2/Detail
