To answer a few questions.
Is it free? Yes. Everyone is welcome to attend. Please bring your friends and family as well!
Are we allowed to come if we don't have any corals to swap or trade? YES, you are most definitely welcome to come by and just hang out and enjoy a beer and hang out with the reef geeks
End time? Last swap we ended around 6:00pm - 7:00pm. It really depends on the attendance. The last one we had over 150 people show up, however it doesn't seem like there's as many people who have signed up to go yet this time around =/
