I think one theory is that Vibrant consumes NO3 in a higher ratio that the normal NO3/PO4 coral consumption ratio. Cyano often occurs when PO4 > NO3. The dying algae can also be breaking down and releasing sugars such that the dying algae is effectively carbon dosing your tank (encouraging bacteria and also cyano).
Vibrant killing all the algae then cyano appears is a common pattern. Since
@GoVols doesn't have much algae in his tank + healthy fish population, I'm thinking he's set up for success more than most Vibrant users.
Guys,
Sorry, we stepped out and had "
Sir Pizza" with our grand daughters
It does seem that the BA could be breaking down.
At this point no signs of cyano, but I don't carbon dose.
Filter sock has been a little dirtier, so the Vibrant might be cleaning some of the low flow areas of the live rock.
Regal Angel is doing great and
has not eaten any sponges with-in the caves of the live rock... yet ;Woot
Fatheads are staying open and (lol) that will be the last time that we stuff it full of pellets.
We also dropped the KZ Genii and one B+ T5. So back to pushing two B+'s with the Kessils.
Got to love, trying

to keeping all corals happy in an mixed reef, when it comes to lighting???
Thanks for tagging and the next Vibrant dose will be on Tuesday evening.
We'll just let the Vibrant play out, one day at a time, like we did the nudi's.
