Help appreciated.

You can see through my fowler now but my fish are starting to stress with the water changes. I have a fluval 205 I am going to try and set up with carbon and wait a couple of hours on any more changes. When I wiped the inside glass it was like an out break of cyano. In my reef my feather dusters come out for a second to test and then close up again. I will continue water changes in the reef but will slow down. I dislike salt mixing in the tank so I will mix and heat again for 1 hour.
Thanks all for the help it has been a horrible day and I hope to possibly explain later.
