Malfunctioning PAM head #3 checked, as per request by Jim Hendee.
"PAM 3 is flooded. Could not pinpoint the source of the leak, but bubbles seemed to be coming from where the cable joins the head. Also, I was playing with Erik’s handy measuring tool and the PAM heads seemed to be closer to the corals than what the measuring tool indicated--can you send me the exact specs for the correct distance/angle from the coral so that when I clean them I can re-position them properly?"
