There have been a lot of additions to the ATO market over the last year or so. The Tunze 3155 Osmolator is stil the best unit on the market. Reliable and dependable. If you're undecided because of price, don't be...just buy it and be glad you did.

Bought one thanks to the positive reviews here and I owe the reviewers here a debt for getting it right and saving Me Money making a mistake.
Want an ATO, click 'ADD TO CART' on this and be done with it.

I recently bought the tunze ato and I had heard many good things about it. I did many months of research and I finally decided to buy it and replace my smart ato which was always failing. I would recommend this product to others

It was easy to set up straight out of the box. This is one of the best investments that I have made for my tank.

This top off is amazing very easy to setup. Don't waste your money on another brand cause it will cost you double and you will end up with the tunze , so buy it the 1st time and it will be the last one you will buy..
Simply perfect By Nate on 12/8/2014

I have used two tunzes osmolators on different tanks and I have never had an issue. double back up (float sensor and auto times pump shut off) makes me not worrying about having water over flow. and all the install hardware added is always a bonus, like the return tube holder.

I have had a few different ATOs but this one is by far the best I have had. Don't know why I didn't just get this one from the start.
