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 9/21/12

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.

Just set up the Tunze top off system what a pleasure to install and complete no other parts needed!

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 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 8/25/12

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 8/13/12

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.
Shouldn't have waited. By Bob on 8/10/12

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.
