ATO gets low, alarm?

[tatties]

hey all, i have the brute 20g bucket that serves as my ato, its hidden behind a wall and crawl space, so not always accessible. i have just installed the apexEL system successfully, love it. is there a way i could implement some sort of alarm that i would know when my ATO water level gets low?

thanks

Very simple.
Add a float sensor or optical sensor to the bin at a inch or 2 above the water pump inside the bin. Setup apex to send notifications alarms etc when it gets low.

so i would i install one of these? drill a hole in the bin, and silicone it?

I wouldn't drill the bin. Just hang a PVC structure inside the bin and attach the sensor to it.

in the 1st pic i placed a pvc zip tied to the pump tubing and wires and attached a float sensor to it just above the pump.

wow, thats fancy

 

[Dr. Reef]

in my ato bin that has 4 sensors.
bottom 2 when low trigger:
1. stops ato pump to run dry.
2. turns rodi unit on when low.

Top 2 are a bit offset on height. 1 is slightly lower than other.
Lower one triggers rodi to shut off and higher sensor is a fails safe to kill it in case 1st sensor doesnt.

Does the EL have inputs for switches? I have a classic and need a breakout box to do this. I have it monitoring ATO reservoir, sump too low or too high.

 

[Dr. Reef]

There are breakout box with USB or (most common) I/O type connectors. EL will work with both type.
