I've been running an emporer 400 along with a Eheim 2217 on my 75g for a year stocked with 10 rainbows, one angel, 4 gourami and a couple panda corys. I'd like to repurpose my emporer for a new project cichlid tank to pair with a aquaclear 110. Will the 2217 be enough to handle the 75g alone? Should I add another canister like a fluval 305 or another 2217?? Thanks for the suggestions.
