I pick this unit up two years ago on Black Friday and it's been running like a champ since. as the BRS YouTube video indicates the laser as well as the mechanical part of this provides a great backup is fairly easy to put together which sometimes is in the case with Tunze Products but this is been doing the job for two years.

I like it So far no issues. The reviews were good. Instead or trying something I am usually using others experiences to save me the anguish of poor decisions
A necessity By JonnyReefer on 3/19/2015

It's so nice not having to get 3 half-gallon cups per day and bend down to refill my sump. And no more micro-bubbles! Although the little nut&bolt that holds the output line to the tank attachment was a PITA to get on, it was a breeze to set up.

Super Product By RDM on 2/20/2015

This was easy to setup and get working. I never realized how much I hated having to manually top off my water until I put this in my system. Now I just check my water levels and the fresh water supply and this takes care of adding water as and when it's needed.
EASY and works great By Jeffrey on 2/15/2015

So far so good ! Have this set up on roughneck bin I'm using to cure my dry rock in. Works perfect and secondary safety offers great piece of mind. In the room one day when pump came on.. manually lifted float and audible alarm sounded and pump shut off. Very comforting to have a piece of equipment like this that is looking out for me ! If you are on the fence, JUST GET IT, you won't be disappointed.
fantastic ATO By Hawrasser on 2/11/2015

this ATO is great. keeps the water level in my sump constant. the only thing i would change is to make the amount of travel on the floating switch a little bit larger. if i turn on my protein skimmer it will sound the alarm but my skimmer is also huge haha
Hoping to get it working By Andrew on 1/16/2015

I have had this on an AIO tank (40 gallon) worked great the first week, now it keeps overfilling my tank( alarm going off) in the process of troubleshooting it with Tunze, hope i can get it to work correctly. I wish it worked right out of the box, but based on reviews the Tunze auto top off is suppose to be the best. I have owned other Tunze products before with no problems. Not bashing the auto top off but its not working out of the box. But Tunze customer service is great at helping.
Great ATO! Never missed the target! By Alec on 1/15/2015

I don't need to add anymore to those 200+ reviews but I put mine on a timer that only turned on once a day for 10 mins. That way it's not pumping all day long and will never over fill.
