  • Good ATO pump By David on 8/15/2017

    Use this pump for my Auto top off and could not be happier. A sturdy pump that is built to last and is rebuildable. Quality pump for anybody's ATO.
  • Good ato pump By Esteban on 6/5/2017

    Great pump for the price. Use this pump as my ato pump.
  • Workhorse By Chad on 3/8/2017

    I have two of these. One is my ATO pump and the other runs constantly to maintain a siphon in my external overflow. Quiet and looks easy to fix if the diaphragm fails.
  • Great product By Jrlafrance on 3/7/2017

    I have always used this pump for auto top off purposes. Not too far in the future I hope to use it as a doser as well!
  • Works great By Stieney on 3/6/2017

    I bought this as a spare since my original unit is more than a year old. The reviews last year were sporadic. So far the original has worked flawlessly.
  • Works great By sokin on 2/5/2017

    This pump is connected to my reefkeeper controller and works well. Quite and great price. Feels like a quality unit
  • So many uses By C on 10/5/2016

    Used these for years, they are great. One of these on a timer works perfectly as an auto-topoff. Also great for keeping the siphon on overflow boxes.
  • Great ATO pump By Josh V on 4/5/2016

    I bought this pump to use with my Hydor ATO and it works great. Fills slowly which is perfect, as I use it to dose Kalk in my top off water. I purchased this with the ATO kit from BRS and everything worked out great.
  • Positive Review By Jason on 2/16/2016

    I am using this with the JBJ ATO pumping up about 3.5 feet. I would highly recommend that you place your air line tubing into a larger tube that will allow air to get into. Doing this will greatly reduce your chance of creating a syphon if using this pump with an ATO. The pump is a little slow and I did have to bump up the time on the JBJ ATO. But overall it is doing exactly what it is supposed to be doing.
  • Very reliable By Phand on 12/19/2015

    I did alot of research on pumps that I didn't have to pump in my ato bucket this one you can out anywhere its not real powerful but it does as advertised and for the price you can't beat it
  • Great cost effective pump By randy on 8/15/2015

    Great little pump. I have it hooked up to a JBJ ato controller, and the controller plugged in to my Neptune Apex. Apex is set to turn outlet on for 13 minutes, then off for 1 minute. This gets around the auto shutoff feature after 14 minutes of runtime on the JBJ controller, as well as resetting the JBJ controller to ensure it runs. Google the JBJ controller to understand these limitations before you buy it.
    It took me a weekend to figure out this combination, but it has run flawlessly since. It effectively keeps 150 gallons topped off.
  • great for auto top off By joshua on 5/24/2015

    This little guy is great for auto top offs. They are durable and cheap to replace which is a huge plus. I've had mine for two years now and have yet to have to replace it. Highly recommended.

Product Questions

Because my top off reservoir is slightly above the waterline of my sump, I've observed that my RODI water will continue to flow into the sump due to siphoning, even after the Aqua Lifter Vacuum pump has been turned off by my ATO controller. Is this normal and what should I do to prevent too much water from flowing into my sump?
Question by: Jim on Jun 8, 2017 5:43:00 PM
Unfortunately this is a common issue with reservoirs where the level is higher than the sump or delivery area. To avoid this, you can install the output tube in the display somewhere, such as in the overflow box, or alternatively you could install a siphon break in the reservoir tubing (basically a small down-pointing hole in the tube or a fitting which will bleed off a small amount of water when pumping, but then suck in air and break the siphon when the pump is shut off.

Hope this helps!

Can i use it as an air pump?
Question by: Armando on Dec 29, 2016 6:40:00 PM
Great question! Unfortunately, this will not work effectively as an air pump. :-)
Answer by: Randy (Admin) on Jan 9, 2017 8:22:00 PM
is there a specified in and out on the pump, does it matter where the tubing is connected
Question by: val sammut on Jan 18, 2017 11:53:00 AM
Awesome question! There are two flow indicator arrows on the top of the red fitting. One is for IN and the other for OUT! :-)
Answer by: Randy (Admin) on Jan 19, 2017 5:21:00 PM
If I used this as an auto top off for my tank can I also use this with a float? Will it hurt to have the pump running while its not flowing because the water is already contacting the float? If so, what would you recommend as a pump/float option?
Question by: Branden Hess on May 11, 2017 8:08:00 AM
Hey there,
We wouldn't normally recommend running a pump continuously against backpressure. This can cause excessive heat buildup and wear on the pump and can greatly affect reliability. Instead, the best way to use this pump would be through a controller or ATO which will turn the pump off when not topping up. A float valve is a fine secondary failsafe, but should not be used as the primary means to cut off flow from the pump. Normally the only constant pressure ATO would be from line pressure from gravity or the pressure generated through and RODI system which isn't relying on a pump to generate the pressure.

Hope this helps!

Do I need special tubing for this? Or can I just use regular air line tubing for this.
Question by: Anthony on Nov 11, 2016 10:09:00 PM
Hey there, thanks for reaching out to us! Our favorite tubing to use with this pump is the 1/4" polyethylene tube listed in the link below. :-)
