[Aheinz]

Throwing this in DIY as I have a inherited biocube 14(not positive) that I've been holding onto for years that i want to rehab into another SW tank or a FW tank fro my room. anyone know what size its supposed to be for the return pipe, and i may have it, but havent looked, also planning to replace the pump as its probably dead lol

Thank you, yeah it's older and I don't have any of the manuals so it's been hard doing research, but I did measure the return chamber so I am looking at various pumps. Wanting to clean it up and get it running as a 2nd tank and do something different with it
