Best ATO out there. Hands down. It just works. Never have to worry about a thing.
Have one for each if my systems and wouldn't do one without the Tunze 3155

What can I say about Osmolator Universal 3155 Auto Top Off - Tunze. Easy to install took me a matter of minutes, being my first one I researched long and hard and this one seemed the best. So far it has been great. I even overfilled my tank myself by mistake and the alarm went off . So far so good a good buy for sure.

Wondering why I didn't install one sooner! This thing is a huge time saver. If you're on the fence, just get it. You will not regret the purchase. Mine has worked flawlessly for months. The only trick to know is to flip the pump upside down & release trapped air bubbles if you ever allow it to run dry & it won't pump after refilling the container.

So I watched the video of Ryan hooking up the Tunze ATO. And it literally took me 10 minutes, taking my time, to set it up. The alarm noise is a hoot. Doubt anyone could sleep through that. Really liking it so far. Teamed it up with a Crystal ATO reservoir from Trigger. Really sweet. The wife approves. Win-win!

I thought, "Meh, I won't mind refilling my freshwater by hand daily"........ well that lasted for two weeks. Absolutely love this thing! Took some tinkering to get it right, but after a day or two I have it dialed in perfectly! Keeps salinity on point and now I can easily dose Kalkwasser. One day I noticed the monitor said "too low," but my ATO bucket was full so I turned it off and back on and everything is peachy again :) You won't regret this product!

Have had for a couple months and has worked perfectly. Tested the safety shutoff and works great. Don't have to worry about sump overflow anymore.

This german made product has lot of magnets and clips and accessories to fit your need. Extremely simple to install. You need to prime the pump when it first starts. Move it around so it can suction the water. I had some cheaper alternatives in the past but this thing works exactly. Didn't have any siphoning after shutoff either.
Good just one issue By Kenae on 8/23/2017

This is a great ATO I've been enjoying it the whole time. The only thing I don't like is the clip that holds the water line into the tank/sump I think that is pretty poor but all in all it's great

The product is easy to instal. Has good instructions and works as advertised. I paired it with the reefkeeper lite.
