Salinity swings due to limpets

[Hunna]

I’m at my wits end here. I woke up to the ATO on my 40b going off once again because the in-water sensor was covered by limpets. This is happening almost once a week now and can’t be good for the inhabitants. Is there something I can put around the sensor to keep these little assholes from triggering it non-stop overnight or while I away from home? A 3D printed cage or something?

The water level is ~1.5” over where it’s supposed to be, and I’m down about a gallon of RODI water from the 5g jug it pulls from that was changed out yesterday.

What kind of sensor is it? Optical?

It’s whatever the duetta comes with

Yep, that's an optical sensor and from doing some searches it sounds like it's a common problem (although all the mentions of it I see are issues with big snails like Turbos).

This sounds like the best solution unless there is some way you can screen that section so that they can't get in there in the first place:

I have the same sensor for my MagTool ATO. I could try to design and print a guard for it before the event Sunday...

But, you may need to poke me and remind me on Friday or Saturday. I've got spring planting I need to get done these next couple of days so I'm liable to be distracted and worn-out.
