I used it for 1 day and it broke. It's not turning on. I think it's just a defect which happens. Brs is going to look at it and I trust they will resolve the issue. Can't wait to get it set back up.
Great design with one flaw By Nick on 1/14/2015

This is probably the most simple ATO I've ever used. I've been using the Tunze osmolator for years, wanted to switch it up for my 220G DD. This is simple, set the eye where you want the sump level to be, plug the clear tubing into the nano sized pump that it comes with, plug everything in and thats it. The flaw is when the you use the full length of the tubing and the water level in the reservoir is higher than the sump level. This creates a siphon, easy fix though, just don't use all the tubing and try to not to have your ATO reservoir higher than the sump!
Nice but annoying By marion on 1/13/2015

I like the ATO and it does exactly what I need but the most annoying part about it is that when the RODI water is low and the alert sounds, you have to physically unplug it to reset it after you have filled your reservoir. A button or an automated function that would reset itself would improve this device a ton. So now you need to keep it in a location where you can easily reach it....every day. After reading some of the other reviews and hearing about the high water alert, I wonder if something is wrong with mine because the alert never sounds when there is too much water.
Bad Operating Design - OVERFLOW ALARM By Pipe Doctor on 12/25/2014
Pipe Doctor wouldn't recommend this product to a friend
I've used mechanical ATO's for several years and work directly off my RO/DI unit and decided to try an electronic ATO. The Tunze was too complicated with poorly written English manual. Then I tried the AutoAqua. Nice with one MAJOR FLAW - I use an Apex Neptune controller and when the system feeds, the return pump turns off and raises the water level in the sump which causes a NON-RESETTABLE overflow error on the ATO. When you feed multiple times a day, this ATO becomes a complete waste. Now I use Avast ATO which I wire directly to my Neptune breakout box which turns on a small pump from my top off water tank. If anyone wants a practically new ATO, look me up on ReefCentral.
Worth the wait By Ryan on 11/30/2014

I waited a couple months for this auto top off to come off of backorder but it was worth the wait this thing works flawlessly and when there is something wrong it lets you know whether it is the eye is blocked or the water is empty to bucket.
Works as advertised By Randy on 11/24/2014

It has been 3 weeks and it has been flawless in my Trigger Systems sump. I do unplug its power when I do water changes,
so I don't get any alarms when the sump level rises. As soon as The levels are back to normal I plug it back in and it resets and runs normally. Best feature is the small pump which slips right into a 5 gallon Jug with no problem.
Nice idea, but needs work By Scott on 11/19/2014

I bought this for my 180 gallon and have it installed in my 125 gallon sump. I have to reset this thing daily. What I've found is that anytime there is an overflow condition the alarm goes off as expected, however once the overflow is corrected, it doesn't reset itself. For example, I have an Apex controller that turns off the return pump during feedings, which increases the water volume in the sump (causing the overflow condition). After the feeding cycle has completed and the water level restored to normal in the sump, the ATO stays in the alarm state. So it won't top off until reset. Which is usually when I get home so my salinity levels increase during the day, then drop back down quickly once I reset.
If your water level in your sump remains fairly constant, go for it. If not, then go with something else.
Small accurate and smart! By jeremy on 11/1/2014

This entire ato is really small. The optical eye can fit in the smallest of sumps or Nanos. The pump is small yet powerful and will fit into just about any change opening you have in mind. I can't imagine this ato taking anyone longer that 2 mins to install. It let's you feel confident that accidents will not Happen. I test things cause I believe an ounce of prevention is worth a pound of cure. This ato will not let itself run for longer than a min with out throwing an alarm. It alarms when it needs water too. Basically it knows it's job and how to do it. It will always error to not add water. Price. Size. Reliability. Intelligence. An easy choice in the world of faulty float switches and over complicated units. Buy this one and save the hassle of the other brands.
Works like a charm By chris on 10/25/2014

I bought this ATO 6 months ago and it has worked just as advertised. I really like how it tops off the water often and in small amounts. Its very quiet and SUPER easy to install. The only downside of the system is that the power cord for the pump is pretty short. You can buy an extension for 20 bucks though. I liked it so much i bought a second one for my other tank. i did have a problem with the second where it sensed that the water was low and started pumping in water and never stopped. I contacted the company and i had a replacement in my mail box in 3 days. amazing product.
overfilling condition fix By Patrick on 10/20/2014
Patrick would recommend this product to a friend
CON: instruction manual didn't tell you everything.
PRO: easy to install, no moving parts (float switches) smart controller.
FIX: must overflow conditions occurs do to siphon not breaking from reserve tank to sump, or aquarium. Using the right amount of return tubing and running your line so the siphon breaks after a fill prevents over fill errors. NOTE: as with any ATO I advise you never have too big of an reserve, only enough so you don't cause salinity issues.
So Simple but robust By CodeWorker on 10/2/2014

After reading many about many other products i got this one. very simple to hook up, easy to use, and works with out any floats. It does keep track of how much water is pumped. so if it goes over that amount it will shut off and beep to let you know there is a problem. I have had it work and protect me from adding to much fresh water when i did a water change. i forgot to shut it off and after it added the normal 2 cups it stopped and beeped. it tops off quick and has worked flawless for 6 months now. I am planing on using one on a 16 gallon nano tank soon.

It's been a year and rocking, not a single beep after installation,simple way to get everything on the perfect level, not frustrating issues with the skimmer, miniature size and 100% reliable.
