puddy????

Putty, not puddy.

LPS is large polyp stony coral. You mean LFS

Really, not much. It's not that expensive for what you use, and other non purpose stuff can have metal shavings or other nasty stuff in it. I think JL is about $12/tube? Pretty cheap.

Or, some people prefer glue. Just regular gel crazy glue is fine. Dollar store stuff.
