I have the 2260 on a 300 gallon tank and I can tell you that it is so good that you can drink the water from the tank. I went for the 2260 becuase it has the largest canister and the most powerful pump that eheim sales, it pumps 2400 liters per hour, and if you are not happy with that you can upgrade the pump to a 3600 liters per hour (beat that 2080) some thing that the other eheims cant doprofil3r;5020802; said:Have a 5feet by 2feet tank, currently running on 8trays OHF with ATMAN powerhead.
Was thinking of further filteration and couldn't decide on either 2080 or 2260.
Any advise guys?
