I will be at your reef at 1pm for a few minutes. If anyone is interested I will bring this stuff.
Milwakee Digital Refractometer. I can't get it to calibrate. It was brand new and worked great before I moved. Now I can't get it to calibrate. The screen comes on. Maybe you can get it to work, maybe you can send it in to get fixed, maybe you throw it away. $30 if you want to mess with it.
3/4" lock line return. Brand new. Bought wrong size ;( . Would trade for 1/2" return in good shape or sell for $15.
Who doesn't need a magnetic frag rack? (me apparently) $10
