I am just curious if anyone has an effective idea/plan for an overflow for a GLASS tank without drilling anything of course. In the future, i plan on getting a larger tank, and i wanted to see what my options are for filtration. one of the ideas i had was a sump made from a rubbermaid tub. It would really depend on whether i can have an overflow that is not at high risk of draining the tank. Also, this tank is most likely going into a bedroom. is there a way to make a sump quiet enough to fall asleep near? thanks!
