Hey everyone, I need some help/advice. Right now I have a 32 gallon biocube setup and running with 2 clowns and some soft corals, I want to add sump to my tank under the stand but I am having a lot of trouble deciding weather to drill my back glass or modify the lid and use a hang on the back type overflow box. Can anyone please help me decide. Also if I went the overflow method what one is recommended for the biocube
Thanks in advanced
Tony

That's kind of what i thought too, I have seen people say they were able drain the back section and drill it like that but idk that's kind of sketchy

I drilled the back of my 29BC and kept the original in-tank overflow. I believe that the return from the sump just came up over the back. Mine used one drain pipe as a full syphon and the other the emergency drain. Here is a video of something sim with a 32BC. Check to make sure your tank back is not tempered.

Why are you trying to add a sump out of curiosity? I have a fairly stocked BC32 and am struggling to keep any level of NO3 in my tank with a skimmer and fuge setup as it is...

Are you utilizing the rear chambers the best you can? IME you can have excellent filtration with the correct gear in these tanks...

Always wondered why folks bought BC’s just to remove the lid, or drill... there are far better options if you want a rimless or drilled/drillable tank. Buying a BC just to gut it makes no sense, since the purpose of an AIO is to simplify things and keep everything fairly contained.
