Noob here!
Hello I am Newbie here and to the hobby. I just got a pre-drilled 75 gal tank. I have decided to make this my long term project so I am planning to do everything by myself or atleast as much as i can. I hope I can find people that are willing to help me through this path of creating a little piece of Ocean.
The tank also has a built in overflow box in that overflow box is where the tank is pre-drilled one of the holes has a diameter of 1.75 inch and the other one 1.5inch. I wa wondering if these are two outlets or one is an outlet and the other one is the return pipe? any help?
