Does anyone know what these are?

[Kev The Fish Keeper]

I brought the tank used, and the person I brought it from found the tank and supplies in attic when they brought the house. My question is does anyone know what these are? They are hardwired into the power box

Those are float switches.

Looks like float switches for an ATO (Auto Top Off) system.

Those are float valves. They turn something off when they are lifted up by the water and on when they are down. I wouldn't trust them personally. They are cheap to replace, and they might fail sooner than later. Welcome to R2R!

If your going to use them ditch the suction cups and find another mounting solution.

Since others have answered your question... just wanted to stop by and say "Welcome to R2R!!!"

Welcome!

I would suggest looking into the Tunze ATO system of you want to go that route.

Specifically, they are low voltage reed style float switches. They must be wired into a relay, NOT directly to the mains. i cannot tell what brand they are, but a quality float switch like the Madison will last for many years.
