These are all good steps. I recently went thru this myself. The black out Def helped just make sure it's completely blacked out. Zero light gets in completely eliminate any source of light from display and the cabinet. I did poke a hole in the car board on top just so the tank can breathe. After that it was just alot of manual removal and blowing off rocks with a turkey baster consistantly for about 2 weeks. I also dosed MB7 this entire time can't tell if that contributed but I Def don't have them anymore.
What about h202? Its been three days so I'm taking it off today if its not all gone should I dose H202? if so does it matter what brand? and will it affect my coral and anemone?
