Thank you very much. We love it (me a bit more than the wife). I am slowly adding more LR to the back section (where the filter was). I took out all the mechanical filter material (sponges) and the bio stuff (ceramic disks and bioballs... dried those out and put them in my FW canister filter... they are nice stuff). I plan on getting some micro algea to put in the back along with live rock and some sponges, etc. Kinda like a cryptic zone refugium type thing. I am hoping that the copepods will dig living in there as well. It is 24 gallons of fun. Would love to have set up a bigger tank, but the cost of live rock would have killed me, lol (and live rock round here is reasonably priced in most places it is around $4/lb.)
