Yes all your numbers are close and we’ll within the ranges if NSW. I jut run my tank on lower numbers. Their are many people that run lower numbers similar to mine have great success. And the other hand, their are many people who run numbers like yours and have great success. Just different tanks.
As for prime. Just 2 different opinions. I don’t see a need to act just yet for a couple of reasons.
1, He is using an API kit which has a track record of giving off false readings at times
2, it was a single head of a torch. As much as it sucks losing coral, it happens sometimes. Even to the best.
3, Everything in the tank looks good. Which leads me to say their is no ammonia in the tank.
