did anybody try the salinty probe modul with the probe

[mcoomer]

I have the SL2 module. It reads salinity in parts per thousand (PPT). I have a 125 so that number doesn't move much but it's nice to be able to simply look at the controller and get the number. I check it with a refractometer when doing water changes.
