Jay99 Posted October 24, 2021 Share Posted October 24, 2021 Title: Eheim Professionel 4+ 600 Canister Filter 2275 filter circulation output Question: What is the filter circulation output (return output to aquarium after water flows through canister filter media) GPH for Eheim Professional 4+ 600 Canister Filter 2275? I am installing an AQUA ULTRAVIOLET ADVANTAGE 2000+ UV 15 WATT BARB x BARB STERILIZER UNIT A00267 on freshwater aquarium. Attempting to determine Eheim Professionel 4+ 600 Canister Filter 2275 filter circulation output rate. The output flow rate is critical to understanding the UV dosage for given circulation output flow. I have contacted Eheim and did not receive a response nor able to find filter circulation output during searches. Fluval does list pump output and filter circulation output specifications. This is the information that I am looking for in regards to Eheim filter.
