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.

Background:

Canister Filters available to place in-line with an AQUA ULTRAVIOLET ADVANTAGE 2000+ UV 15 WATT BARB x BARB STERILIZER UNIT A00267:

         Eheim Professionel 4+ 600 Canister Filter 2275

                 Pump Output: 317 US Gal/h (1200 l/h)

                 Filter Circulation Output: ? (US Gal/h unknown

          Fluval 407 Performance Canister Filter A449

                   Pump Output: 383 US Gal/h (1450 L/h)

                   Filter Circulation Output: 245 US Gal/h (930 L/h)

          Fluval FX6 High Performance Canister Filter

                   Pump Output: 925 US Gal/h

                   Filter Circulation Output: 563 US Gal/h

 

Data below found at Aqua Ultraviolet site

Organism Killing Dose of UV light measured in Microwatt seconds per square centimeter (uw/cm2)

     Viruses: 15,000

     Bacteria: 15,000 - 30,000

     Algae: 22,000 - 30,000

     Fungi: 45,000

     Protozoa: 90,000

 

Recommended Flow Rate for UV Dosages:

          at 30,000 µw/cm2 (EOL) GPH: 700 (Max Flow Rate)

          at 45,000 µw/cm2 (EOL) GPH: 466

          at 60,000 µw/cm2 (EOL) GPH: 350

          at 75,000 µw/cm2 (EOL) GPH: 280

          at 90,000 µw/cm2 (EOL) GPH: 233 (Min Flow Rate)

Note: All UV dosages are calculated at the end of lamp life (14 months). End Of Lamp Life (EOL)

Depends on head height. So the answer is some GPH less than the 330GPH it's rated at. The only true way to know is to attach a flow meter at x head height and see what you get.

I was hoping to locate a source of reliable data pertaining to Eheim Professionel 4+ 600 Canister Filter 2275 pump and filter circulation outputs. 

Unfortunately, individual may end up with a canister filter that does not meet needs if counting on data resulting from filter purchased and then tested. 

I do not currently have a flow meter, but that appears to be equipment worth investing in. I will research possibility to install flow meter in the output line to see filter performance going down. Looks like excellent means to catch filter performance slipping and implement maintenance before flow drops below need.

I also use the Eheim 2217 classics. I modified it with an in-line pump that has that kind of data available. Not sure you want to go that route but it looks like this.
