Sump Help

So I have a 120 gallon I am attempting to setup and have a 20 gallon sump I could use, would I have issues? I want to be able to have some macroalgae in the sump because I own a kessil 3 light for growth I guess my concern is maintaining enough water in the sump for that but also having enough room for the water in the case of a power outtage

Issue would be if power goes out it will definitely overflow. You can buy a bigger used tank. I'd go that route

Ya I hear ya. Just throwing it out there, that will be something you need to think about unless u can configure a check valve of some sort

What about a 40 breeder? I have a 20g under my 90 and I don't think I'd go any larger of a tank with a 20g

That's not true... to determine if it would overflow you would have to calculate the volume above your return/overflows and compare to the excess volume in your sump. You can't make blanket statements like that.
