Replacing the water evaporated form your tank is a chore and nightmare for every one in the hobby. so when it came for me to setup my 120 gallon tank this was one of the first piece of equipment i got for my reef. i must say simple to install and reliable it has never failed on me or flooded my basement. if you want simple reliable this is for you.

Bought this after getting fed up with making top off water everyday. A little pricey but it comes with everything you need and is easy to set up. The optical sensor is nice and was a selling point for me.

I have had saltwater aquariums for 20+ years. Iwork offshore and overseas.I have to depend on someone to check on my tank on a daily basis to add water. This Product was very easy to set-up. I tested it by turning off power, removing water and adding water, and it works great. This tank can go a week without supervision now...Probably the best piece of reef equipment i have ever bought.....Well worth the price!!!!
Best ATO By Chris on 10/13/2012

Seems like lots of money compared to some of the other ATO but it's worth it. Nice to have something that is reliable and gives great piece of mind that it's just going to work.

I've had mine for over 1yr. It's never given me the slightest hiccup.
I use a small reservoir for top off water (2.5g jug). My jug has run out of water on a number of occasions. The pump included in this unit is very durable. I think most other pumps would of been smoked by now.
Works Great as an RO/DI ONLY Top Off By Toby on 9/20/2012

Works great as an RO/DI ONLY top off but I would not trust it to top off with KALK. The optical sensor works great! This product will help you enjoy the hobby.

This is one of the best aquarium devices. Just add water to the top off container once a week and forget about it. Easy to set up and the magnet holders work great.

Have been using for a week now and love it. Don't have to worry about if the wife topped off the sump or not while working a 16 hour shift. I come home to a always level sump. Made life easier!
I finally caved, and I dont regret it! By amber on 8/25/2012

I heard people talk about auto top offs or ATO for months but balked at the prices.
I finally got fed up with making buckets of water and dripping it all over the place every day to top off my tank, not to mention the stress it put on my fish if I forgot to do this one day and the water level dropped!
I finally splurged and bought this one after reading all the positive reviews and I have to say I am in love!
I bought an attractive kitchen trash can with a lid to fill with water and keep it next to the tank. I only have to fill it once a week which is awesome. It has even run dry and the pump still works like a charm (not that I recommend doing that).
Its a sturdy easy to use and worry free way to keep your tank at the optimum levels and I highly recommend it!
Love my Osmolator! By kenny on 8/25/2012

Purchased my Tunze Osmolator for my 70 gallon rimless cube reef tank about eight months ago....it keeps my Specific Gravity at 1.025 and it is very easy to set up, one of my favorite purchases for my tank. No more manual dosing top off water for me...Purchase an extra pump as you may need a new one in 8-12 months.
Great System By Will M on 8/13/2012

I never realized how much easier keeping my tank topped off would be until I ordered this unit. Excellent system and as long as I weekly fill up my top off water container I'm set. No more bi-daily pouring RO into my sump. A+!

This product is a little pricey but is well worth it. Auto Top off made simple. 2 switches (one optical and one mechanical) create a fail safe design that keeps your salinity perfect at all times.

It took me a while to order this product because of the price. It is worth every penny. I no longer have to worry about daily top offs. I have a 125 gal. tank, and use a 5 gal. bucket as the top off. This lasts 1-2 weeks. It was very easy to set up, and has worked flawlessly . I highly recommend.
Absolutely Amazing By Colin on 7/25/2012

Great Product! By paul on 7/19/2012

I have had this unit for over two years. It works great and I have had no problems with it. I love not adding top off water every day! I use a 20 gallon Brute trash can for my RO/DI top off water and that lasts me two weeks for my 240 gallon tank. If you are going to use it with a kalk Stirrer I would recommend using a PH controller because if you have a small leak or start doing a water change before you unplug it, you could get concentrated kalk into your tank pretty quickly.

Do not hesitate to purchase this the price point is worth it the peace of mind and lack of necessity to spend the daily fill up is worth every cent and on top of that the wife will actually like the functionality of this piece of equipment.

Everyone should own a Tunze auto top off. Really easy to setup and works great. This is a perfect device.
Great upgrade, don't have to worry about water top offs everyday. By Moises on 6/17/2012
Moises would recommend this product to a friend
This is one of the best upgrades you can add to your system. Yes the price is a little high but your paying for a high quality product that is fail safe and will give you peace of mind. Not to mention no more daily top off chores. The system is easy to setup and the magnets make placing the sensors hassle free and give you the ability to place them where ever you want. If your going to buy a ATO system this is the only one to consider.
Top Notch Product By Jeff on 6/5/2012

Can't beat the quality of the Tunze Osmolator and BRS price and service. The dual sensors and sturdy magnet mounts provide peace of mind. I feel safe with this system.

Have had it for a while now and rely on it completely. Have never had an issue with failing in the on position like float switches tend to do. Would highly recommend.
Magnet holders are also a plus as placement is a snap.

Its my first time purchasing an ATO system, after seeing the price I did not think that I was going to buy this system, but after knowing that its fail safe I decided to get one. It works awesome and I would recommend.
