I bought a used small canister (eheim ecco 2232 ) on Amazon that I'm planing to add it to my existing 125g. The main reason is that the small gph will allow my 9w UV to run efficient.
What I want to know is if there are any health risks for the fish associated with this ? (the used media came clean and dry).
Thanks
