hygger Aquarium Alarm Auto Top Off Kit, Fish Tank Smart ATO Water Pump Auto Refill Water and One-Key Drain Water, Water Level Monitor Two Pairs of Protection Sensors for Saltwater Freshwater Tank

Material de buena calidad, tamaño muy discreto, fácil de instalar, me encantó que el sensor no queda adentro del acuario así evitas que este se ensucie y además cuenta con doble sensor.

I am amazed at the amount of evaporation that occurs in my tank. This works great and is simple to setup and adjust. The only thing I dont like is that the alarm is load and persistent. This of course is a good thing when water is low. I just wish the alarm was a bit more quiet and not beep as often. Its all my preference the product works like a champ.

Where to start. I have a bunch of fish tanks, and topping off tanks and doing water changes/refills is an area where i'm always looking to save time.Enter these ATO's. Pretty straight forward, three ports, a sensor to see the water level, and in theory reversible flow but I never used that feature.One of the three units I bought just never worked from day 1. I think I was sent a replacement for that one.The other two though, have been intermittently failing (not detecting water so no filling) or running beyond where they should have shut off.After the three to six month mark, I was basically fiddling with these things multiple times every week to get them to work, which defeats the purpose.Everyone loves Hygger stuff, myself included, but not these things. These are junk.See the video for how this one failed.

Superó mis expectativas, muy buena calidad, pequeño, tamaño discreto, silencioso, no me vuelvo a preocupar por los niveles de agua de mi acuario.

Once it's set uo it works well, if it has any issue though it beeps nonstop.
