Fiji Cube Silencer for Automatic Roller Filter ARF-20

No idea how this is supposed to silence anything, no instructions nothing.

Works to quite it down, however without instructions I can't figure out how to install the 2nd piece and also keep the float sensor installed. Also, I contacted support multiple times without response to figure out how to have the roller automatically enabled when it gets power (it requires you to press a button each time). Without this ability I can't control it from my Apex controller to turn it off when I turn off my return pump for maintenance.

Nice
