I set this tank up for my GF's apartment while she goes to Pharmacy school. Tried to make it simple with easy-ish plants and fish. I actually had this set up since October or so, but just am now getting to posting this journal.
Obligatory tank specs:
Custom LED light, 3x cool white LEDs, 3x neutral white LEDs, 3x royal blue LEDs, controlled and driven with a LEDGROUPBUY dim4 controller
ehiem 2232 w/ do!aqua intake and cal aqua labs nano outflow.
5lb co2 w/ azoo regulator and diffused with a do!aqua music glass
ADA amazonia NEW multi type
hardscape: Hakkai stone (super rare apparently) and manzinita
Plants: Cyperus helferi, trident javafern, mini pelia, Fissidens fontanus, starougyne sp 49, belem hairgrass, HC

Ok, and on to the pics.
Custom stand made out of an old Ikea desk
Custom LED fixture. I used 9 left over Cree LEDs and used this controller http://www.ledgroupbuy.com/dim4-4-po...ntroller-v1-0/
It's pretty sweet, you can actually run up to 12 LEDs on it up to 500ma without the need for a separate driver, so for a small tank like this, it's perfect. It' can even do sunrise/sunset features. I'm using 3 channels for each of the LED colors and the last one for the fan. I tried out a new style of building the LED light, instead of doing strips, I clustered them like on the Aqua Illuminations LED light, this way, I can easily blend the colors and get the optimum color temp, while still getting the spectrum I need from the cool and neutral white LED. The only draw back is that you'd need a lot more LEDs. For this foot print tank, I probably could've gotten away with maybe 6 LEDs. Even at 9, and with the optics on, the spread is only ok.
PAR readings, this was at about 18 inches off the ground. Good thing I had the meter back then, I was able to dial it in exactly the intensity I needed.
And finally, here's the tank with everything set up and light mounted. My dad and I built the light cover, and painted it white to match the rest of her furniture.
Here's the tank as of yesterday. Everything is growing in nice and slowly, which is perfect for her since she doesn't want to have to do maintenance on it. I have her dose brighty K and bright k special lights (2 pumps a day) yes, i know these ferts are expensive and whatever, but i got a good deal on them and this is the easiest way for someone to dose a tank.
thanks for looking!
