Announcements
June meeting is Friday 6/6 7:00 PM
Due to unavailability of previous scheduled program, our presentation will be given by our club member Devin Duerst, who happens to be the chair of our Breeders Award Program (BAP). So besides his presentation, bring your questions about the BAP and find your way to elevate your status within the club.
He will give a short presentation on how he keeps his fish room and the evolution of how he keeps his tanks from filtration to water change, and will host a discussion on the pros and cons of different filtration methods.
