"Show me your Biocube mods"
 

I am looking for some ideas on how to sump out a 12gallon biocube, I will be doing a DIY stand at some point in time for the 10-20 gallon sump to fit underneath. I am looking for some Ideas on how to do this and make sure that I maximze flow, effecientcy, and environmental standards for the life inside the tank, as well as minizming any problems, such as flooding or leaks.
thanks for the input

Drill the back glass on the center chamber. I've read the bottom is tempered, so you can't drill it. I've got a biocube 29 that I wish I'd drilled, but instead I went first with a custom 3/4 pvc siphon overflow and then a cpr cs-50 overflow. The pvc overflow wasn't reliable and while the cpr is more reliable, it required cutting the trim off the back of the tank, a big chunk out of the back of the hood and needs a very high water level in the tank. I suspect on a bc-12 there wouldn't be enough room for a cpr cs-50 anyhow.

Cool thanks that helps me out alot, all I see on DIY stuff is the Overflow boxes on the back and I doubt Ill have enough room! I hope I cn find someone to drilll it more me. and you think the middle chamber should be drilled? no the sides?

Well on my 29 I would drill the back glass panel about 1/2 way down in the middle chamber. You'll have to decide if this would be appropriate in your tank.

my question to you is why the center? wouldnt I want a drain tube on one side while I have the over flow on the other to maximize my filteration?

I'm not sure how the chambers are set up on the Biocubes, but if I were to drill a Nano Cube, it would definitely be the centre chamber that I drilled. I would still use a media basket in the first chamber for filter floss, Purigen, and charcoal. I would want all of the water to pass through that into the second chamber, where it would then flow into the sump. I would have the return from the sump entering the return chamber, though I know some people have that coming into the centre chamber, too.

10-20 gallons isn't a big sump, and there is only so much that you're going to be able to squeeze into it (especially if you're going to build a fuge in it). Continuing to utilize the first chamber for some filtration is going to help save space in the sump: for things that absolutely need to go into the sump.

Yha I have my plan all drawn out, I was just curious where and how to place my holes and what the best efficentcy will be for the system :P thanks for the idea though and I have also seen people use the middle chamber as their refugium as well so who knows! I do want to drill and sump out the tank though

adn does anyone know of any good threads for step by step to help with modding the biocube? I have tried finding some but havent had much success with step by step files

yeah, for my biocube all the filtering is in the sump, so it's just most convenient to use the center camber because it is the biggest.

Know of any good threads out there for help on this build?
