Water testing results

[Acronuts]

Very interesting on test kits and results. Yesterday my test results using Hanna and Red Sea were as follows:
Ca = 506
Alk = 8.96
Mg = 1400
No3 = .04 - Red Sea
Po4 = .13 - Red Sea
Today I had the water tested at my LFS and they use Salifert and my results were as follows:
Ca = 450
Alk = 9.23
Mg = 1470
No3 = 0
Po4. = 03
Do these numbers look out of order? Should I be concerned?

They are likely fine.

Only possible concern is very low nitrate can begin to starve corals for nitrogen.

How does he tank look?
