This seems to be working like a Charm. However I did have one issue with it right away, for some reason the pump wasn't working when I first plugged it in. I unplugged it for several hours and came back to it to see what the problem was and when I plugged it back in everything worked perfectly. It has kept my tank at a perfect level so far. I have it hooked up with a 5gal tank reservoir and it has given me less time worrying about water level and more time loving my tank!

I love this ATO!!! I don't ever have to add more water to my sump day in and day out. I have a 10 gal sitting inside tank stand and it lasts about 1 1/2 weeks before having to fill it again. There has been a few power surges since installing it. It has never failed to come back on or sound alarm. Thank You Tunze and Thank You BRS for carrying this item.

This unit has not failed once. I use Kalkwasser in my auto top water and the pump hasn't failed yet. The pump is a little bit loud but the BRS staff told me to pull the airline tubing out a little bit and it made it much quieter.

I have used the Tunze for two years now and it meets my expectations. One needs to take seriously the caution to not have the feeder hose under the surface of the aquarium water level. I flooded my office twice doing just that. Also, the pump has a 6 month to a year longevity and they go out without much fan fare. Keep a couple extra pumps, at 23 dollars, on hand. My final caution is not a fault of the unit but I have an auto feeder in my lower tank and when the feeder was too close to the optical sensor flakes of food caused the unit to think the tank was at level and it failed to fill. Keep the food as far away from the sensor as possible. Beyond these concerns, it is a great unit and very dependable.
Gold Standard of ATO By Keith on 9/4/2014

The system comes with everything you need to get an ultra-reliable and well built auto top off system in place on your aquarium. This is a must if you want to keep your parameters consistent and your tank running as it should. Make sure and put the rubber feet on both halves of the magnets to keep them from sliding around. I love the redundancy of an optical eye, a mechanical float switch and then a timer on the pump.

Wonderful product that has made my life easier By David on 8/15/2014

I was a little skeptical at first installing an auto top off. I had fears or dumping 30 gallons of fresh water into my tank with a faulty device or switch. Having this up and running now for awhile has been great! The sensor is very sensitive and adds small amounts of water throughout the day. I also like the back up float switch. It was easy to set up and the magnets make adjustment simple. I now fill my top off container every several weeks and that's all! One piece of caution is to watch the placement of the top of container as you can get a siphon started. Great product!

I purchased this device a year ago and I cannot begin to explain how wonderful it has been since. No more daily top off. Now you can just sit back and enjoy your aquarium. Coupled with an automatic feeder, you'll spend less time worrying about your fish and coral, and more time enjoying your tank!

I got this about 3 months ago and it is great! Easy setup and it keeps my water where it needs to be. I am home and watching my tank all the time but this is just a great tool to help with top off!

This is a great product by tunze all-around. the only problem I had with the unit is that the metering bump broke shortly after I received the unit. but I contacted tunze and the quickly replaced the pump at no charge.
Working great. Shutoff redundency By John on 7/7/2014
John would recommend this product to a friend
I have been using this in my 75 gallon or approximately 18 months. It has been working flawlessly. I originally had the sensor in my display tank and when I introduced a sump, I moved the sensor into my sump. I am using RO/DI water with no Kalkwasser added. I like that there are two mechanisms to shut off the unit if the level is higher than it should be.

Really not much to say as the product is excellent quality and works. Do yourself a favor and don't cut corners on an ATO.
