Auto Top Off for Saltwater Aquarium Water ATO System for Both Reef and Fresh Tank - Blue

This was easy to set up. It is small and discreet. It has stabilized the water level and appears to work as expected. The sensor does what it was created to do. So far, so good! And the price point is perfect.

I bought this ATO for my nano saltwater aquarium and would not buy again. It failed twice in about 4-5 months. The magnet is not strong enough so any large turbo snail can push the sensor up, making the water level go up. Also, the glow of the light is annoying at night. Pay more money now for a good ATO with a strong magnet and a cover over the light sensor

Excelente producto muy buena precisión y fácil de instalar

Honestly one of the best purchases I’ve made for my aquarium, although I don’t use it for its intended purpose. I use if for water changes, putting the pump in my aquarium with the sensor off to the side, and the water goes into a bucket, and for refilling I unplug the sensor, move the pump to the bucket of new water, put the sensor in my aquarium as indicated in the instructions, and then plug the sensor back in. It is so, so, so much easier than getting my siphon started, stresses my fish out WAY less, and creates way less of a mess too. It obviously doesn’t work for vacuuming gravel, but it’s made maintenance on my aquarium so much less stressful, and freed up a decent chunk of time too.

Muy bueno el producto comple perfectamente con lo especificado
