Bio cube as a sump

[benc2428]

I have a 75 gallon tank and a 29 gallon bio cube. I am trying to turn my 29 gallon bio cube into a sump for my 75. Does anyone have an ideas on how to do this if it’s been done before and where to start? This is my first time ever using a sump and not sure where to even start.

show us a pic of that bio cube ….you have space issues or just repurposing the biocube?

I’ll post a pic of it in a minute. But I have it sitting and don’t get enjoyment out of it like I used to. Also I have the 75 that’s been up and running on hang on the back filters so I thought it would be a good option to just use the bio cube as a sump or if there was a different route that would be better to go down.

I would be selling the BioCube and buying a 20 high, 20 long, or 29 gallon to throw under there. There are some baffle kits made for all of those. Biocubes have a nice following and would probably be sold quickly for half what it will cost you to build the purpose built sump.

I agree. Only around 75-100 bucks depending on local prices and taxes to build a nice little sump.

100% agree.

I think it took me 2 hours to sell my biocube a few years ago. If it intact, and in good shape, won't take long to sell it.

Plus it would be tough as a sump with the baffles in the back, and the curved glass would make baffles impossible.
