Review on 🐠 Eheim AEH1260310: The Ultimate Universal Aquarium Water Pump for Optimal Performance by Kathy Sabo

Over 30 year old model still in production! When paired with a larger pre-filter such as an ATI Max #3 filter instead of a small standard pre-filter, the impeller will stay cleaner longer. Good pressure for small Mazzei Venturi protein skimmers (484x) or as a return pump. Big and heavy like a '57 Chevrolet, but man, it drives great. do you want more flow? Order a pump cover (volute) for 1262 and Alt, you will have an 898 gph pump instead of 635 gph for 1260. See Volute 1262 is like a hood scoop for 57 Chevy and lets more air in, I mean water in the pump. Pump. They designed the pump to run at 898 gph and then installed a more restrictive volute to only deliver 635 gph. Power consumption increases or decreases (up to a certain limit) with magnetically driven AC pumps, depending on the limitations of the volute or tailpipe. A kilowatt meter can easily show you that, because 1260 in standard form uses about 60-65 W. Change snail 1262 and it works ok. 80W! Without a kilowatt meter, you can do a 5 gallon bucket flow test in 15 seconds. Measure/weigh what was pumped into the bucket, then multiply by 4 for your 60 second flow rate. Then multiply the flow rate in gallons per hour (GPH) by 60. Run this test on each coil and see for yourself.
