you gotta watch this stuff, it's not joke! I had a buddy who was working in his tank not wearing protection, scrapped his arm on a jagged piece of LR, as it turns out his tank was loaded with zoas/palys and it got him good, his arm blew up and he had a very harsh reaction, as matter of fact he is now afraid to stick his hands in his tank and sorta lost interest in the hobby all together after that incident..
