Turn my biocube into a sump?

[rickybutler]

Hi i'm fairly new to this DIY section and have some questions out there to you experts! I currently have a 14 g biocube with 40lbs of LS around 2o lbs of LR, 1 firefish, 2 occ clowns, 1 fireshrimp, 10 BL hermits, 7 snails, green ricordea shroom and branching hammer. I have a refugium in the 2nd chamber also. I want a ghost eel/blue ribbon eel badly and want to turn this biocube into a sump for my new 55-75 gal tank. How can I do this? How do I plumb it? Can I keep my fish/coral/inverts? I'm going out to look at new tanks in 15 mins so when I get back hopefully I'll have some answers!!!! thanks!!!

ribbon eels are kinda hard to keep.....
but anyways, if all your wanting to do is plumb the 2 tanks together to get more water volume for the new tank (which is what it sounds like to me since you are talking about keeping everything in the tank...) I would just put the new tank higher up than the cube and have a HOB overflow on the new tank that drops into the 1st or 2nd chamber of your cube and have a return pump in the 3rd chamber that you can split off for flow for the cube and return for the larger tank.. The only down side of this is that you are going to need alot more powerheads in the new tank to keep the water cirulating since you probably can fit a very large return pump in the cube spaces...or plumb a canister filter inbetween??

So i would have an overflow in the main tank with pvc draining into my cube with a large pump in the third chamber which would be split into sending some back into the cube yet most into the main tank? I was going to get a couple powerheads one of my LFS is going out of business and they have all the kinds of Koralia pumps and other wavemakers 50% off!!! So im going to get most of my equipment there, maybe a 75 gallon tank with a built in overflow with space for a skimmer and heater for around 200? is that a good price and option?
