AutoAqua Smart Level Security

My aquarium is not drilled. I use this in my HOB overflow for piece of mind. The overflow is the weakest link in my system. My tank water line Is low enough (barely, lol) to accommodate all the water in my sump in the event I lose siphon. My sump is large enough to accommodate all the water that would flow into it if my sump pump failed. What this does is shuts off my sump pump if the external portion of my overflow gets clogged, because it’s obvious that that chamber cannot accommodate all the water I have in the sump. Yeah, if the external chamber of the overflow got clogged there would still be water on the floor. But it would be a much more limited amount. I tested it and it does work.

This device is basically a switched outlet with a “change of state” sensor that works like a circuit breaker and has an alarm, and it has to be reset each time it its triggered, either by cycling power to it (turning it off and on) or unplugging it and plugging it back in. This device is capable of two different types of operation, either sensing a drop in water level or sensing a rise in water level. It only can do one of those at a time and will not function like a float switch, as in it won’t turn on and off repeatedly as water levels change. It is a one shot/one time switch until you cycle power to it. Once power is applied it goes through a 4 to 5 minute boot up/set up process. During that time it senses what you want it to do based on where you placed the sensor, as described below:Option 1-Low level sensor: Place the sensor below the water level and then plug it in/apply power. The outlet will energize and beep for several seconds while flashing a blue light. It will continue to flash the blue light for 4 to 5 minutes until it is finished setting up, and then it will turn solid blue. At that point it is now monitoring. If the water level drops below the sensor's position, the outlet will “trip” (de-energize) and begin flashing a red light while also making a slow beeping sound. This will continue until you remove power from the device/unplug it. Even if the water level is restored to normal, the device will remain de-energized and in alarm until power is cycled.Option 2- High level sensor: Place the sensor above the water level and then plug it in/apply power. The outlet will energize and beep for several seconds while flashing a blue light. It will continue to flash the blue light for 4 to 5 minutes until it is finished setting up, and then it will turn solid blue. At that point it is now monitoring. If the water level rises above the sensor's position, the outlet will “trip” (de-energize) and begin flashing a red light while also making a slow beeping sound. This will continue until you remove power from the device/unplug it. Even if the water level is restored to normal, the device will remain de-energized and in alarm until power is cycled.Something to watch out for: If the water level changes while the sensor is in the middle of its five minute flashing/setup cycle it will affect the desired setting. This could be an issue after a power outage when water levels may shift while the device is going through its 5 minute start up cycle.

It’s not listed anywhere but you plug it in if the sensor is below the water when plugged in,it will set as a low sensor. If the sensor is above the water when plugged in, it will set as a high sensor. It also takes longer for the light to stop blinking and turn solid as a high sensor, mine took 15 minutes to set as a high sensor! Works really great just not explained how to switch between a high and low so I wanted to here

Worked great for three weeks, then stopped working

I have numerous saltwater tanks. I know from first hand experience that skimmer overflow (especially external overflow containers) can damage aquarium cabinets and floors. This fantastic little device is inexpensive, easy to setup and fabulous peace of mind. I have one on each if my tanks and really love them!

Awesome product, saved my butt several times because I forgot to turn my rodi off

Amazing product keeps my protein skimmer from overflowing

Great product.
