I have two used salinity refractometers if anyone is interested. I am happy to give them to anyone in the group.
I have one for @MolaMola that she bought from another member awhile back that I was supposed to give her next time I see her, but we haven’t had any events for awhile. She may want one and is out in that area.I have 2 refractometers I can give away for free as well. Can meet at Diablo Corals in Concord or All About Fish in Pleasant Hill most days after 4PM or on weekends.
Thanks @Coral reefer
