I ended up having an optical in my ATO reservoir, a tri-optical for the ATO with a float back up. Then I have an optical almost to the bottom of my AIO as an emergency run dry alarm. I also put an optical sensor on the intake side that stays dry and alerts me when the sock gets glogged and...

Ok, I will give that a try. I’m still waiting on some sensors that were on back order. Thank you.

I have a water level sensor submerged to just above the return pump. It is to prevent running dry. I want to have an output that turns off several outlets (hydros powerstrip basic one) if the sensor returns dry. I have tried generic and combiner. Neither work. I can select the water level...

Need some help with a scenario. I have a water level sensor (underwater) just above the return pump. If the sump runs dry, and triggers that sensor that it changed from wet to dry, I want to turn off the return pump and the heater. I cannot figure out how to do this. I have tried both...

So what would be better? The float switch to detect low water levels in my AIO or the optical sensor? I can’t do both, not enough space. Same for the ATO supply, float or optical for running low?

I think I may have answered my own question while adding Hydros things to my cart. They have a HYDROS Water Level Sensor That I was planning on getting for the ATO jug. Since it alerts when the jug gets low, I am assuming I can put it down further into my AIO just above the pump and if the...

I had a run dry situation while on vacation. My ATO failed and never topped off the tank. If you saw my post on R2R, you know what happened. But I lost all fish, most inverts, clams, and anemone. I was recommend Hydros for its flexbility and reliability. I am looking at the XP8 AC strip...
