Great ATO Pump!
Very effective for using as an ATO pump, handles head pressure very well!
Great pump for my Nano ATO
Easy to use and performs perfectly.
Mighty little pump
Great pump, super powerful but a bit too loud for my taste. I found it vibrated a lot when it was on so I added closed cell foam to both inside and outside of the cover and used double sided tape and stuck it to my sump. Now its just as quiet as an aqualifter. Easy thing to do if the noise level bothers you. Well worth the purchase.
Great item. Small but powerful pump
Does it's job
I've had the Avast ATO system for some time but never bought the diaphragm pump as I've been using a converted powerhead. That powerhead finally went out on me and decided to get something a bit more fitting, literally. So far so good! It's got some noise with it when it turns on, a bit louder than the powerhead, but the flow rate is better since there is no need for jerry-rigged tubing adapters now. Looks better, too, and allows me to get nearly all of the water out of the reserve when I'm waiting on running water.
