Ok so im back after 10 years had a 55g freshw simple angle tank. I picked up a 125g acrylic tank that is drilled only 1. 2in hole behind the weir. I really dont want to get into a sump filter thinking a fulva fx4. But i do not know what to do about this hole. Do i hook the canister up to it? Or just put a bulk head in and plug it. I plan on doing a planted tank and only having a few bristle nose plecos and a betta in it. Nothing more for at least a year. Fyi in my 55g i had 5 angles and some guppies. With 2 bio wheel filters rated at 75g a pice. Thank you. I have not set up anything yet because i need to wet sand and polish the tank still.
