For $200, I don't get a finished product? By Mike on 5/15/13
Mike would recommend this product to a friend
I haven’t set it up yet and I’m sure it will work as advertised, but it contains a feature that is a pet peeve so excuse me while I rant a bit. The pump connects to the controller via two bare metal wires that have to be manually wired to a “terminal” connected to the controller. The manual does not explain how this is to be done. I got instructions from Tunze and had the strong impression that the rep thought I was either lazy or stupid for asking. I may be both, but when I pay more than $200 for an electrical product, I expect it to be fully wired. What would it have cost Tunze to add two snap in parts to connect the pump and the controller? A few pennies extra for each piece? So why didn’t they do it? I suspect because Tunze, like other major manufacturers of aquarium equipment, assumes that they can cut corners and the customers won’t complain. Well, it’s really no big deal, right? But what if you bought a top of the line coffee maker for $200 and it required that you wire the plug to make it work? Would that be ok? How about the numerous Chinese manufacturers who provide instructions for their product in absolutely incomprehensible English? I could go on. But if this kind of thing occurred in any other consumer market, there be an outroar. But since it’s just an aquarium product, we just shrug and look for a work around. IMO, we deserve better

I have had this product running on my 125 gallon tank and it has been a life saver. However, it started malfunctioning and I had to return it to Germany to get fixed or replaced. It cost me $35 to ship it there and that was the cheap route. It has been 1 1/2 months since I shipped it out and still no contact from them.
What a Great Product: By Bruce on 5/9/13

For anyone that wants peace of Mind about their aquarium, this is the product for you. An accurate, automatic device that will add DI water or Kalkwasser to your Sump is the way I use it. Perfect for the person that makes short trips, without the worry of evaporation causing your salinity levels to rise while your gone. A perfect 5 from Me.
A MUST for larger tanks with large evaporation rates! By RandoReefer on 5/7/13

After upgrading to a 125g tank with a 30g sump, I noticed my evaporation rate upgraded also. One week of manually topping off 1.5gal per DAY, was enough for me to pull the trigger on this ATO.
I really trust the sensor on this system! I was close to buying the JBJ Auto Top Off but I'm so glad I put up the extra money for this one. It is sleek, provides a variety of setup options, VERY Accurate, and easy to setup. I gave it 4.5 stars, because it could have used a few more directions or a FAQ section.
Why didnt i get one sooner! By Jason on 5/1/13

I finally made this purchase and its a life saver!
comes with everything needed (except water container).only issue is the
eye sensor gets micro bubbles on it when first installed which causes it to pump water continiuosly till high level alarm shuts it off.best advice is clean sensor with vinegar and let it sit in your sump for a couple days then its trouble free.
The best hands down. By Alex on 4/13/13

Tunze osmolator top off is the best system you can buy. Well worth the price, comes with its own pump and has 2 different technologies working flawlessly to protect your tank and home from a flood.

This is my second unit i'm ordering, first one was about 2 years ago. This is for a second setup, the first one is doing great. The one problem with these is the power plug. After sometime it becomes corroded and you get strange errors like overfill alarm wont stop. But if you have any problem the first thing to do is take off the 2 screws and clean the port and the plug. I cut a nail file down to about 1/8" to clean the port, and just a drill bit to scrape the plug inside. worked great and im good for another 6 months at least. At some point i'll just solder the wires and never deal with it again.
Worth every penny!!! By Steven on 4/4/13

You do get what you pay for... Keeps my water level constant. Love the optical sensor they use on this system. No brainier to install. Now all I need is to make something to hide the top off container...
awesome product By brian on 4/4/13

I recently upgraded my 60 gallon reef tank to a 180 gallon. With my 60 I just topped off the old fashioned way but that was getting to be a chore with the new tank. I was on board with purchasing an auto top off but had serious concerns about failure...particularly in the on position. Virtually every other ato product out there was peppered with negative reviews regarding failure. We have thousands invested in the tank so it was worth it to spring for the osmolator. Piece of mind and very easy to setup. Skimmer works a lot better to.
