A MUST for larger tanks with large evaporation rates! By RandoReefer on 5/7/13RandoReefer would recommend this product to a friendAfter 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 5/1/13Jason would recommend this product to a friendI 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 4/13/13Alex would recommend this product to a friendTunze 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.
great ATO By illya on 4/13/13illya would recommend this product to a friendThis 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 4/4/13Steven would recommend this product to a friendYou 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 4/4/13brian would recommend this product to a friendI 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.
Amazing By Dan on 3/27/13Dan would recommend this product to a friendProbably one of the best investments I have made in this hobby. A really solid product.
Excellent product By P Duffles on 3/25/13P Duffles would recommend this product to a friendI'll simply agree with the multitude of people praising this ATO. This thing literally changed my life :D
The best By FISHY on 3/25/13FISHY would recommend this product to a friendThe best thing that you can do to your tank.
Good Top Off Bad Instructions By Mike on 3/25/13Mike would recommend this product to a friendThe instructions on this top off could be WAY easier to understand if it didn't have 6 different languages on each page. Also, it should also state in there that you need to soak the opitcal sensor in soapy water and gently wipe off the polishing residue on the sensor before installation, also there is a dial on the inside of the controller that you need to set depending on the size of the aquarium or sump that you place the sensor in, the dial basically sets the dosing the pump pumps water into the tank/sump. A little better instructioni pamphlet would give this product 5 stars!
Great product!! By Bosley on 3/15/13Bosley would recommend this product to a friendI have this running on my aquarium and it is spot on and fail proof . the back up plunger has not been activated Probably because the top off system works so efficient, Great product recommend to anyone who is tired of adjusting or just having other systems that fail.
Not Cheap..you get what you pay for By Curtis on 3/10/13Curtis would recommend this product to a friendBest ATO available

What does the Pump connect or hook into for its supply of water for topping off? Do you need another piece of equipment of does this hook into your home's water line?
Bulk Reef Supply Hey Robert,
The pump would be placed inside of a container of water. A 5g bucket is a pretty typical option however it would not be capable of connecting directly to your homes water line.
by Loraine on April 14, 2013, @4:48 AM
Are there pumps for use with this system that will work at more that 7 feet?
Bulk Reef Supply Hey Loraine,
If you would like you can purchase the tunze osmolator switch socket adapter. This gives you the ability to use the tunze osmolator with any pump you like. Something like the BRS 50ml Top Off Doser would be a good choice for a longer distance.
