Ok so i just got a 34 cube and i am having it drilled so i can do a sump. I need help with advice on how to get it done so it is quiet. Do to the small size i am not sure how to lay it out and how many holes or where they should go. I need to tell the glass shop where to drill and what size. I am use to larger tanks like 180 plus so this tiny tank is new to me. Please help, only necessity is quiet.
