Boy did that suck! I'm coming up on my 3rd year Reefing and have only had slight mishaps, But this was a DOOSEY! Know I know how you guys feel after this happens! Probably stressed my fish and corals all out, Broke some @#$% off and dont have a place for a huge Monte Cap know!!! O well it was bound to happen, Worse thing is I have a 3 foot acrylic hex and the rock was stacked all the way up the back.
