Review: Simple but effective ATO for small tanks - I bought this to use as an ATO for a Fluval EVO 13.5 saltwater setup. I didn't want to spend a ton of money on an electronic ATO for this little tank and didn't have the space in my office for one. This was cheap and simple so figured was worth a shot. I've had it on the tank topping off the 3rd chamber (return chamber) of the tank for 2 weeks. It has kept the water level constant and I have not seen any variation in salinity (checking using refractometer). The constant water level has also made the PS2 protein skimmer run more consistently without having to fiddle with the micro adjustments any more as well.
Review: Really surprised how well this works - This product saved the tank in my office. The AC is off on the weekends and the water was evaporating too much before I could get back to refill it on Mondays, and the water parameters were swinging too much. With this guy, I set it up in a about 3 minutes and now every Friday I fill this up and pop it on top of the tank, and the water level stays constant all weekend no problem. One other nice feature of this is you can choose the size/style of the bottle you want to use, to better fit your situation. I just use a small .5 liter bottle and it works great for weekends, but if I am going away on vacation I can use a 2L bottle and things will be fine for longer. Great product!

## Questions & Answers

**Q: For aio tanks what chamber do you place this? i have a waterbox mp25**
A: I place mine in the pump chamber because it’s the first water level to change. I have a waterbox mp15, a cube20, and a Nuvo 10.

**Q: My water bottle is getting compressed from the pressure, any suggestions or ideas on why this is happening and what to do about it?**
A: I think you may need a new water bottle. I jave used mine for several months and they did not compress.

**Q: Will this work on a tank with black trim?**
A: As long as the trim isn't thicker than 10mm it will work.  My all-in-one tank has this top off on the back black trim and it works great

**Q: So i just set up my ato on my community tank. the 2l bottle i'm using just collapses. anyone have a recommendation for a more rigid bottle?**
A: Easy fix! Smartwater bottles work like a charm. The racetrack gas station by me sells 1.5l bottles. I have 4 of these units and these are the best bottles I have found to date.

### ⭐⭐⭐⭐⭐ Worked exactly as intended
*by A***R on January 10, 2020*

I couldn't be happier with this product! I bought this to maintain my water level while I was away on vacation for a week. In the winter my small (5 gal) aquarium evaporates off water very quickly, and if the water level falls too much my heater and pump turn off - which is no good for a tropical aquarium. After finally locating the Evian water bottles it requires, (I had to buy a case, which cost almost as much as this product) I assembled the filler, (which was very simple) stuck it on my aquarium, crossed my fingers, and left for vacation! I half worried all the water would drain out, overflow my tank and ruin everything while I was away, but when I returned, the water level was right where it needed to be and there was no indication of any spillage. It had used the entire bottle in that time. The only limitation to this product in my opinion is the capacity, since you are limited to the size of the bottles you can locate, but for me, 1 liter was enough for 1 weeks time. I would highly recommend this product for an effective, inexpensive top-off device.
