So I bought a new Cobalt MJ1200 and cant decide how to use it
- I could replace the old Cobalt MJ1200 I use for my reactors (nothing really wrong with it)
- I could replace the old Marineland MJ900 I use for flow in my refugium
- I could use it to mix new saltwater and pump it in during water changes
- I could add it to my overflow or sump to help keep stir detrius

although I'm not sure you're really asking
