I'm looking for input on running a GFO/Carbon reactor (BRS) on my 90g. It's walled on 3 sides so I can't do a HOB unit. I have a cabinet above and below the tank. I suppose I lean towards doing it above the tank if it'll fit because I can have a backup way for water to get back into the tank if there's a problem.
Anyone run a system like this above their tank?
If I run it below, I believe my pump would need to be stronger than what's typically suggested. Thoughts on that?
Thanks!
