I have had my Hydros Control 4 for a few years now (3-4) and I really have not taken advantage of it. It's been plugged in taking power without anything connect to it. My Tunze ATO failed and I figured that I should look at using this controller.
Questions since my experience with the Hydros has been kind of mixed. I have a small 13.5G Nano.
#1. Does the controller support using the Hydros ATO with two optical sensors (or the rope sensor) to prevent overflows? I saw that Danny, above, mentioned that only one optical sensor is supported. I prefer some level of redundancy.
#2. Is this ATO a bit to strong? I currently use about 1/4 gallon of water per day.
#3. If the answers to the previous questions are not great, then would I be better suited to buy the cheaper MagTool Optical Sensor AUTO TOP Off(ATO) and then pick up a Hydros water sensor to control the wifi strip in order to cut the power if the primary sensor fails?
#4. How is the reliability on the Hydros Control 4 units? What benefits do I really get from using the Hydros ATO in my scenario vs. the MagTool? Does it tell me how often it goes on and off or any cooler metrics than I saw in the past?
Thank you in advance!
