ATO Auto Top Off System for Saltwater Aquarium NewGen One Long Life Design with Dual Optical Sensor for Both Reef and Fresh Tanks (NG ONE)

First thing – the use of magnets is pretty cool, and they hold! I have 2 turtles and they like to mess with things in the tank but this has remained in place! Issues: 1) It is hard to see the indicator light, I wish it were brighter. Looking at it straight on is the worst. It is best visible from the side of the sensor. 2) The way it is shaped, it is not possible to raise it to the very top of the tank so the water will not rise as high as I like – it is blocked by the lip of the tank (plastic piece all the way around for setting pumps, light hoods, etc. on. 3) The pump is a little slow. That’s not a huge deal as I do not intend to use it – I will be wiring the pump power to a soldenoid driven valve and attach it to a water source – NO buckets! :) I’ve tested it, it has plenty of current to drive a small RO water solenoid valve. 4) It worked great through the first bucket of water. There was still a few inches in the bucket but I saw no lights on the sensor. I unplugged power, waited 10 seconds, plugged back in – no light. I pulled the sensor, let the water drain out, lightly shook it, set it back in the water – no light. I pulled the power cord connectors, and reconnected them. Now I had power when I checked. Pump came on, water started flowing again! Nice little design, not perfect, but certainly works!! [...]
