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
CodeWorker would recommend this product to a friend
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 works too! yes more expensive but super easy, appears to be reliable, and good for reefers like me that aren't too "tech-eee" and don't wanna worry about 2 float switches and keeping them working properly. just do it, do it.
awesomeness By ReeferDre on 8/15/2014

I've used a good amount of ATO over the years and this is by far the easiest to set up,use, and clean. The directions could be a bit better but as a product itself absolutely awesome. I wish all reefing products worked as well as this. I have replaced the all ATO's I have with these.
Works as described, no problems here and easy set up!!! By Michael on 8/6/2014
Michael would recommend this product to a friend
Set up was super easy, I installed it, tested it, and have been using it problem free. I needed a good ATO to stabilize water levels in sump. I'm using it on Aqueon Proflex Sump #3 and its a great addition. My OCD made me use some 3m stickies on the output tubing holder instead of screwing it on the acrylic and it holds great! Ya, it's rockin' like Dokken lol!
Works awesome in Picotope By Ben on 7/18/2014
Ben would recommend this product to a friend
I have this ATO in my picotope and it always keeps the water level within 1/4" in the tank. Pump is quiet and I've never experienced the beeping issues that other's have talked about.
My no hassle procedure for a water change is:
-Turn off ATO
-Replace water to level where I want it
-Turn ATO on
Done, no alarms or anything like that - going on 6 months with this unit.
Durring setup you love it but then... By shawn on 7/2/2014
shawn wouldn't recommend this product to a friend
The safety features sound great but seem to also cause headaches. It is set with a 48 hr no fill alarm that isn't mentioned in the booklet. After setup if it's not activated to fill within the 48 hrs the alatm goes of with blue light. The book says the blue light means misalignment or the lense needs to be cleaned. So you clean it and check alignment, reset it by pulling out power plug. 48 hrs it goes off again. If your tank doesn't evaporate that quickly I dont see a way around this repetitive annoying alarm. It could be a very nice little ATO but appears to be to smart for my setup.

Use with float switch for backup By pleco on 6/21/2014
pleco would recommend this product to a friend
It works well most of the time, but should only be used with a back-up float switch to turn it off in case of high water level. Product worked flawlessly for me for the last two weeks until this morning when it malfunctioned and overfilled the sump, emptying the 10G reservoir over the course of one hour.
Best ATO ever By Nickbruh on 6/4/2014

I have a 15 gallon rimless cube with sps and Los and designer zoas
I was a big beleive in toppin off manually everyday ... Mad was I dumb with this ato I mean it comes with piping , a pump, I mean literally everything and was so dan easy to setup literally don't let the 149$ price tag fool you, this thing is fool proof I've been in the game for 6 months so I'm new to it if I knew this was the best ato I would have gotten it earlier , iHaTE float switches thy are ugly and too much wiring for me especially for a smaller tank with no sump a know
Awesome Product By lwood on 5/24/2014
lwood would recommend this product to a friend
Very efficient and easy to put together, not at all complicated like most ATO's easy of use is 10/10. Sleek design for smaller systems such as mine. I will give it a 7/10 on price but it more than makes up for it in efficiency.
Wow. Works as advertised. By HappyRC on 5/19/2014
HappyRC would recommend this product to a friend
Keeps my salinity in check. More importantly, when I am away from home for more than 1 week, my water level would get so low that I'd risk my overflow running dry. This ato device assures that my overflow will never run dry.
My acrylic aquarium is a little thicker than the 1/2 inch that the product says it can do so I taped some Velcro below it to keep it from sliding down.
NOTE: the device must be attached to a CLEAR glass/acrylic.

Looked for quite some time for a good quality ATO system for my sump tank. With very limited room to work with, I finally narrowed it down to the AutoAqua ATO-Glad I did! This ATO is small and effective!. Very easy to set up and operate. Had one small alarm glitch which was quickly remedied by a call to tech dept. Quick reset and problem solved. Definitely a great purchase and addition to my set up! Thanks AUTOAQUA and BRS!

This is my first ATO so I really can't say if its worse or better than any of the others. However I can say it works exactly as advertised and id super small and includes a pump! Installation is a breeze and its compact size and no moving parts sealed the deal for me. Great product good job AquaAuto!

I just received this ATO from BRS today. I had it up and running in less than 10 minutes. I have very limited space in my sump at the moment and I was still able to squeeze this baby in. The pump is so tiny I was skeptical but it sure does push some water! Time will tell how reliable it will be, but so far I am more than pleased. Great product at a great price. Thanks Coralvue and BRS!

i used to have the JBJ and wanted to replace it with this product. this product was awful. It would empty my ATO chamber and my sump would be completely full which would mess with my skimmer levels.. also it would beep all the time for no apparent reason.. My JBJ was not broken and i have now learned the meaning of "Don't fix what isn't broken."

What an awesome ATO system. By Timbo on 2/22/2014
Timbo would recommend this product to a friend
This ATO is amazing. It is compact, accurate and the pump while smaller than you can imagine pumps water like crazy. Its also complete - no need to buy a pump separately like some other ATO systems. This little ATO keeps my water level just where it should be without taking up valuable sump space. I have a 220G reef tank with another 70 gallons of sump and this keeps it topped off without any issues.
Other reviews have complained about the length of the cables that run to the ATO being too short, but CoralVue sells extension cables for this, with which you could make it as long as you need. I can't imagine a better ATO system being available at any price - if you are in the market for an ATO look no further. Buy this one and don't look back.
