yes i did zoo.... i am aware of the directions.. but its a light chemical doesnt affect the fish at all!!! reason is im wondering what happened is that i still have on more orino... and hes doing fine through the process.... no color changes or anything.... but the other two.... after 10min spurt after acclimating they started to get dark... and very weak... and so.. on.. and ....so on.. till their death... black on top of there head.... instantly i knew something bad was going to happen.... i think the black color was from stress and netting....
when i move fish i remove what ever amount there old tank is from new tank then fill new tank with all water from old tank net the fish and put them in....
