Also, since this is a build forum/challenge, I will do my best to answer questions and update when I make changes. I have been running the factory filter sponge with the carbon and bio rings, and last night I cut a Poly Filter piece to go on top. I plan to change out the filter media every 2 weeks, or more if necessary. I'll try to run this tank more "CLEAN" than usual because I am reaching with the SPS specimens I have added and I usually just grow out softies and various LPS in nano tanks.
