So i was at a venders house trying to get a gift for my boyfriend and i ran into a strange situation. The guy took the coral i purchased and prepared it with a bath of some kind. When i asked what he was doing i got a strange and vague reply. It made me suspicious enough to look up the bottle he was using. Why in the hec would he be bathing corals in an insecticide. My boyfriend doesn’t even let me clean near tank cause of chemical contaminants. Is this normal to do? And what’s the purpose of this? Is it to stop algae growth like he said?
