I built this tank and fixture over the last couple months and am now ready to start stocking with softies.

If you have any questions feel free to ask, just to get started all of the equipment used is listed below.

The idea of this tank is simplicity so I am going with a softies only tank there is a glass top to prevent evap, and a ceramic airstone for gas exchange( per the glass lid ). Also I will be doing water changes weekly and fine tuning that if needed just for starters. Dosing ?? Not sure yet but I think it might be pointless on a 3 gallon tank thats getting weekly water changes.

 

1/4inch plate glass

aquarium silicone

glass holes bulkhead

danner mini65 pump

ceramic airstone

 

Heatsink - http://www.heatsinkusa.com/ 7.28 by 9 inch $19.50

 

Leds and buckpucks - http://ledsupply.com/ 2 buckpucks w/pot and 5 royal blues and 5 soft whites LEDS $122.05

wow great looking build. How much were the materials for the tank? How many hours have you put into this so far? ;)

 

Thanks for showing such great build pictures too!

The glass cost me $45 bucks to have cut, and the silicone costs 12 bucks. Also had to buy some glass drill bits and a glass hole saw that was about another $25. Plus I had to buy the bulkhead $5 and the danner mini65 $20. As for time I prob have a total of 6 man hrs in the tank and another 8 in the light. It just took alot longer overall because of dry times and waiting for supplies to come in the mail.

Love the look of the all aluminum fixture. Nice detail on the power supply plug and pots.

You used way too much epoxy though. If you ever need to replace one of those you're going to have a hard time. I use a small amount and had to remove a few of them and was a pain.

That is a great tank now if only i could figure out how to build something that high quality

 

 

I already had to remove 3 LEDs that were bad that I should have tested before gluing them down. I had to use a hammer and a chisel but after a few light taps they popped off. The amount of epoxy you see is excess that pushed out around the led after I firmly seated each LED with a twisting motion.

Yeah I knew that was excess after pushed firmly but even at that point, its too much though. It doesn't really hurt... just ease of removing later and overall aesthetics. Maybe I'm too picky. When I push my LEDs with thermal paste I barely fill the holes for the screws in the star PCB so that gives you an idea how much i use :lol:

A nice trick to remove LEDs glued with epoxy is with a crescent wrench and adjust it to fit the star and just twist. That way you don't have to scratch the heatsink or damage the LED or another one when hammering or using screwdrivers and scrappers (like I did the first time)

 

Tank looks great BTW :D keep it up

Nice led setup what did you do for the edge's those are the Aluminum C- channel what did you use to do the 45 cut and then what you just drilled the C channel in the heatsink and attached it with some metal srews..? like it..

Ya I just bought the c channel at home depot. Cut the 45 s with a chopsaw and then just used some small nuts and bolts to piece it together.
