Aquaclear 50 with AC 20 impeller test video.
My order from Ken's Fish came in today. It included a Aquaclear 20 impeller. So I did a test to see if it would reduce flow on the Aquaclear 50. It does, but it's hard to get it to prime. I may get a AC30 impeller to put in it so I can use it on my 10 gallon. I'll enjoy the benefits of a huge media compartment with reduced flow that's right for a smaller tank.
