What Radion is it?
That should be fine though.
You are running a higher alk with low nutints it looks like. What’s the Po4?
What else are you dosing , Aminos fuel mb7 vibrant ?
BJD is usually a secondary infection , once flesh rots the virus moves in and colonizes. It can then spread.
Like the flu, you have to be exposed to virus and be half unhealthy to let it be effected. OR have dead flesh make a nice home for it.
IMO , bjd in the flu scenario would present right away, if the flesh rots it could develop.
It’s the sad case sometimes in younger tanks the alk and ph aren’t settled in quite often and nutints and bio filter just aren’t stable to process, either higher nutrient loads that lead to cyanos alge etc, or are processing faster than its being fed,
The true zero zero scenario , and staving corals or one sided nutrient limitation scenarios , Dino’s chrysophytes etc.
As far as the bloom , get air inthere , think about air fresheners and look for dad snails etc.
