I found a very cheap Fluval 32.5g freshwater tank, I'm looking at the specs of the Saltwater v Freshwater versions on the fluval website and they seem to be near identical besides the internal hood light. I'm not sure if changing out the Aquasky LED to a Marine 2.0 is possible/been done before? If anyone has any insight on turning this tank into a saltwater compatible one, that would be very helpful!
