Recently had about out break of Cyano bacteria. I'm on day two of a black out and starting 24 hours after my lights were off started getting a very fishy low tide smell in the room. Is this normal because the bacteria is dying off? I am on day two of a black out and starting 24 hours after my lights were off started getting a very fishy low tide smell in the room.

Cyano bacteria and have a smell while doing a 3 day black out.

Recap:
Day 1 black out. The smell began in the evening fairly strong
Day 2 smell increased. I did notice that the cap on my skimmer was not tight. But the smell was strong above my display tank
Day 3 very little if any smell.
Day 4 I’ll be turning my lights back on
Not sure if it was the Cyano dying off that cause the smell or if it was a sliggtly loss skimmer cap.

I think you are likely correct that what you smell is dying organisms. Likely the bacteria. When I had an outbreak of Cyano about 2 months ago I tried every trick in the book to eliminate it. Rarely did I make any progress. Ended up going with ChemiClean as a last resort. That was a fantastic decision. 72 hours later it was gone. So I had fantastic substrate, white and looked good. Bumped up my lighting intensity just 3 percent in the last two months and I'm now dealing with a brown diatoms outbreak. Those diatoms saw that blank canvas and took over. Funny how that works. Out of the fying pan and into the fire. That's a long way of saying, your new lights will be brighter and likely played a big part of the initial increase in cyno. If you are adding other supplements, with out as those can be hidden sources of food for algae. But what you are dealing with is very common for a young tank. So don't panic. Keep trying things like watching the food sources for such bacteria. I concluded I did not have enough circulation in my tank which caused fertilizer Eds of detritus to fuel the spread of this cyano. remember, I'm a year in. So expect this type thing to happen on young tanks. Take it slow and don't panic.
