Biocube as a sump tank

[Flyntm08]

Thinking of using my biocube as a sump for the 120g i want to set up. Has anyone repurposed one and what did your ingenuity turn out?

I'm sure it could be done, but I'm not sure how efficient it would be to use an AIO tank as a sump. I would suggest getting a DIY sump baffle kit and a 40 gallon breeder tank, and keep your Biocube as a quarantine tank, or as a side project/second tank. Just my $0.02. Good luck!
