Adding a sump without drilling.

[Reefcube29]

Adding a sump without drilling your tank. Is it a possibility or just a far fetched dream. I know I can look into a hang on refugium, but want to see if there are any other options out there. Since a hang on doesn't really come in anything bigger than just a few gallons which is pretty much a waste. Any and all options and opinions appreciated.

Pick up a overflow box. They aren't the ideal option because there is a small risk of it breaking siphon and you ending with some of your tank on the floor..... But I've used one with no problem. Ask around for a used one to give a go

Go for CPR Overflow box. have them for a year, with the pump. Might need to replace the pump soon, but it work great.

Also, better use a actual sump then hanging a big refug.

I had a lifereef overflow box for years and never had a problem with it. good design and high quality boxes. they were the only company that guaranteed no siphon break.
