This tank has been set-up for a couple of years now. It was originally a 10 gallon with LPS, but after moving and suffering significant losses, I took the opportunity to design a SPS doninated nano.
The tank itself is 18 gallon tall (20 x 18 x 10) and I circulate it to a 5 gallon sump underneath using an external overflow. In the sump is where I have a Tunze Comline 3100 skimmer. I also have a kalk reactor that I made, but because to some chemistry issues of late I have not been using it. Despite this, to keep sucha small system balanced in terms of salinist, I made a top-off system using a number of float switches.
Well for lighting I have a 250W HQI metal halide with a 14K Pheonix bulb. Its housed in a canopy I made myself and it is run with a Coralvue electric ballast.
As for current inhabitants, all I have is a blood shrimp (aside from various Astrea snail and hermit crabs). I used to have a pair of percs, but a little experiment I had killed them. Anyways, I had also been waiting till after summer to get any fish in case I go away for a vacation.
Thanks for looking!
