I've heard you can't use canister filters for saltwater because the salt will corrode the metal (unless you get a super fancy one like a fluval that is made with titanium alloy)
I want to set up a brackish 55 gallon and I'm wondering what to use for filtration. I will probably stick a sponge filter in there but is there a type of canister filter I could use? I'm hoping I don't have to do a back-hanging filter because I want to do a waterfall type thing.
