Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
is that used to seal seams on tanks? if so then fine. i ve never used that though. Are you trying to create some huge aquascape of live rock or something? Wondering why you need so much. I use crazy glue for small jobs. Larger jobs if you can hide it, a few zip ties work fine. if you have a drill, just drill the two rocks and zip tie them together. Use a little epoxy to secure and done.
