12G long - HC, shrimp, fish, CO2, DIY LED


I've been lurking on here for a while and really liked finding pics of the Mr. Aqua 12 gallon tank, so I thought I'd add mine to the mix.

Equipment:
Tank: Mr Aqua 12G Long
CO2: Paintbottle with GreenLeaf Atomic regulator
Co2 reactor: Griggs style DIY
Solenoid: Clippard Mouse
Heater: Hydor inline
Filter: Eheim 2217
Substrate: ADA Aquasoil
Ferts: EI, dry mixed with water in pump bottles
Cover: DIY Glass cover

Flora:
HC grown immersed
Repens 049
Microsword

Fauna:
40ish Red Cherry Shrimp (from Epicfish)
12 Harlequin Rasboras

Startup issues have settled down and the tank is looking pretty good. During the first month, I had diatom algae (brown cottony type all over the bottom), some kind of white spiderweb type of algae, and a week or so of green water. But these are all gone now...yea!

I currently have a bit of staghorn algae that I am dealing with. Mostly just physically removing what I can. Slowly upping the CO2, reducing the photo period and making sure I keep up with ferts.

My shrimp seem to be doing ery well. They don't really eat much of the algae wafers that I put in occasionally, but I think there is plenty of algae on the rocks that they seem to love.

The DIY LED light is working nicely. It is 8 3W Cree with solderless connectors, Carlco optics, and an aluminum I-beam that I used. The I-beam works well...it shields the light from view as well as hides the driver in the top.

Day 1


After 8 Weeks

I had a few questions on what I used for the LED fixture, so I thought I'd include that here.

I got the parts from www.reefledlights.com. They have a pretty good DIY materials on their website. I was also considering www.rapidled.com, but they did not have a solderless option at the time, but they do now, so I would consider them as well.

The JBJ solderless connectors worked pretty nicely...they were very easy to install. You just have to drill 2 holes in the heat sink.

Here are the parts I ordered from them...

8 Cree XP-G R5 LEDs
8 JBJ Solderless LED Connector with two #4 Self Tapping Machine Screws
8 BJB Optics Holder
8 Carclo Optics
1 LPC-35-700 48V 700mA Constant Current Driver
1 Arctic Silver The... 3.5 gram syringe

I already had some wire that I used and I got the aluminum I-Beam off of [Ebay Link Removed]

The amount of light for the 12G Long tank seems to be pretty good. I don't have any basis for comparison though. The other aquariums I've had in the past were quite a while ago and were T12 flourescent. Everything seems to be growing pretty well. I lost the Downoi that I tried, but I added that pretty early in my cycle, so that may have been the issue.

8 lights seems to be about right for this tank. There is no spotlighting at all.

I was debating about getting the dimmable vs the constant current driver and decided with the constant current. I think that is fine...I probably would have run it at full power even with a dimmer. I can raise/lower the fixture to increase or decrease the intensity.
