Hi, so I have this 160 gallon tank. I bought it as a freshwater tank and I'm currently moving to saltwater, I want to add a sump. It seems like the best way to do that is a hang on overflow box, but I've also heard it can be a problem if the siphon breaks. I don't want to drill a hole in the tank, and I don't really want to use canister filters, so what would be the best way to do this?
Thank you
Thank you
