nice. In all the years that ive been keeping saltwater, ive never done a dual sump, so this will be my first. Ive setup sumps for a few of my buddies and they are pushing alot of water, with custom return setups. 70 gallong tank with a sump and skimmer rated for an average stock 300 is a pretty decent setup. Later i will be adding a seperate refugium to it. we shall see how that goes. come june, ill get some more pics up of my setup and let everyone know how its going.
