Anyone ever seen a biocube used as a Refugium? I am upgrading tanks and got the idea. Didn’t know if anyone has done this or thinks it’s possible. Anyone?

Had a 75g display with sump and used a 14g BioCube as a remotely dedicated fuge by removing the false wall, elevating above the sump with a gravity feed through a drilled hole in the back of the cube for PVC plump to return section of the sump. It was simply fed from an MJ600 in the baffled section of the sump.
If I can retrieve a pic from Photobucket I'll post to show you how I had it.
Never seen a Biocube converted to fuge but no reason it can’t be done.. I’m using a little 4 gallon AIO as a fuge on my current build.
You just gave me an idea. If I get a bigger tank I could use my 29 as a sump/fuge. Remind me of this...
@Mordie101 sorry for the cruddy pic. It was one of the old cheap digital's from ~2009
This pic is from 2011 and I had run it for a few years before the date of the pic. I cannot retrieve the pics of building it but perhaps this old pic will give some kind of idea about using a BioCube.
Sorry, it is all I can retrieve. Photobucket is so hard to get anything from nowadays. argh.

I bet Octoaquatics could make a director for your water to have a controlled spill over.
Great! So basically you removed the plastic wall, drilled a whole in the back and just let the water fall out into the sump? You fed it with the pump and just kinda had the feed hose held into the top of the tank?

Yes, I drilled the hole toward the top of the back glass after removing the false wall, used a bulkhead for attaching PVC to drain to the return of wet/dry sump then used the MJ600 with vinyl tubing over the top of the BC adjusting to input to return ratio. It worked well and never had an overflow of fuge nor sump if I did a power off test. Worked quite well with a small PH in the fuge too.
Great! Thanks for the reply and the advice! If I do this I’ll be sure to give credit where credit is due!!
It just always been fun to try different stuff like that. Once I drilled a 5g and used it as a remote fuge on a shelf above a 29g BioCube. haha, Crazy part is that it worked great.
I just wish I had better access to ~7,000 pics on the dreaded Photobucket. argh.

Quick question.. where in your sump did you put the mj600? Would I put it before my skimmer or after it or in another compartment all together?
