Sorry for the blurry shot, I've been told my ccd has become dismounted :-/ This tank hold a little over 26 gallons when filled to the overflow. It is made out of 3/8 acrylic and has a 2" lip around the entire top. Being that, it's an open top tank The OD of the tank is 36" long x 18" wide x 12" tall. The water line is at 10" inside the tank, leaving a little over an inch to the bottom of the tanks lip. The bottom is painted white as I'm not putting any substrate inside this. The background was painted blue because I couldn't stand to look at that much white. The overflow will be enough whiteness, along with the blinding bottom. I have acrylic trays I drilled out for the frags, 2 of them are pictured above. These two are for larger frags/colonies. I have smaller ones for smaller frags. All available space was drilled out on all trays allowing for maxamized flow thru. Lighting for the tank is the new Icecap Spot pendant with 150 watt 6500k metal halide flood version and a Icecap electonic ballast my Icecap Spot Pendant review My thread on the Icecap Spot Pendant in the Lighting forum I'm using a new overflow design (at least to me) and a Stockman standpipe, which is fairly close to what Fletch came up with on his own Gresham overflow with Stockman standpipe thread Water movement will be provided by both an OM Squirt ( www.oceansmotions.com ) and Tunze pumps ( www.tunze.com ). Roger of Tunze USA is currently helping me design which pumps and controllers will be used. I'm going to use a Tunze as my return pump as well For a skimmer, I'm going to get a Euroreef cs-8-2 (0r 3) EXT or RC model. I'm going to utilize yet another Tunze pump to power that For auto-top off, I'm using a Cole Parmer Masterflex parastatic dosing pump that will drive a custom made Nilson reactor. To add in alkalinity, I'm using a DG88 calcium reactor design with my own touches. This tank is inline with my 30g (soon to be 36"x18"24", 10 refugium and 10 gallon sump.
