Looking for milawauke salinity reader

[Cobystolz]

I am looking to trade for a milawauke salinity reader. I have a good amount of random coral I can frag to trade. I also can 3d print something or something’s. I have made phone holders that suction to the glass for time lapse, seahorse perches, tunze osmolator control box mounts and a few other things and can make custom parts. I also have a ro buddie reverse osmosis system.
