Is it possible if I don't like how an overflow box looks like, to just have my holes drilled in my aquarium with a plastic mesh..well maybe not mesh, think of the drain in a below ground pool or those things that hold urinal cakes,but scale it down to about 3inch diameter, would that work? or do you 100% need one? just wondering, I don't really like the way they look.
