Hello reefs.org! I just joined and wanted to share my 10 gallon kitchen nano that I setup last summer. Here it is… Set up is as follows... lighting is a 2x36 watt ahsupply retrofit PC, with bulbs from hellolights.com (one 10,000k and one actinic). Above the tank is a 7 gallon refugium (drilled plastic critter keeper) with two 15 watt NO "Lights of America" kits from Home Depot that cost about $7 a pop. I run those 24/7. In the tank I have two Minijet 606s at each corner (upgraded from original 404s) and I have an Aquaclear 150 HOB on the back, drilled to fit another Minijet (404) that pumps up to the fuge. The fuge then gravity feeds back to the tank via the HOB. I have another powerhead in the fuge for circulation, which helps grow the macro. I have an ebo-jager (I think 150 watt) in the fuge. I drip about a half gallon a night of kalk (sometimes full strength with 1 teaspoon/gallon, sometimes ¾ teaspoon, depending on pH and alk). Lately I’ve been adding straight calcium chloride on top of that as my tanks become a hog. Calcium stays between 400 and 450. I try to keep my alk around 3.0 meq/L. I do a little over one gallon in water changes a week, and am up to 10 mL DT's phytoplankton every other day, on top of Selcon and a whole slurry of frozen things I feed, as I have many filter feeders including my nonphotosynthtic orange gorgonian (Swiftia sp.). Inverts are too many to list, but include softies, LPS, SPS, and four clams (three maximas and a squamosa). Blah blah blah... I'm happy to go on and on about this tank, but would rather go back and forth with questions... I'll post a bunch of pics...
