If gladly put the t to good use of you wanted to part with it. Can offer a frag or two for exchange. I'm heading to Mattapan on Tuesday to set up a tank sometime in the late morning/early afternoon.

Shoutout to @TPhan for hooking up the Tropic Marin Hydrometer today, much appreciated.

I have one of these I use to calibrate my refractometer every month or so. Works great, just make sure you store carefully!
