Neither are good test readings for SW fish yet - 9-10 reef fish in 30 gal's minus rock displacement - well maybe a decade from now if ever unless of course you like watching marine life suffer and die. I've only got 7 fish in my 210 and nitrates are below 5ppm it took well over a year to get nitrates low enough to grow corals. Nitrates will drop to 20ppm at some point took my tank 9 weeks after the first fill - 20 ppm is fish safe anything orange or red is not good enough. Each time you add some type of life nitrates will climb back up to 40 or more wait til they are back down to 20 then add another. The largest jumps in nitrate occur from adding and feeding fish - it can take a month or even 3 months before nitrates drop back down - hence take it slow. It will take several months for the super saturation of calcium and magnesium to occur within your system testing for it will show you - not a bad thing to know.
Anything live in water in a bottle or bag is going to be an ammonia bomb - it is sealed, no exposure to the air ammonia goes nowhere. The exceptions being frozen or refrigerated this stuff is loaded with phosphates it is naturally occurring. Just cause you can't see the copepods doesn't mean their eggs didn't survive - this is called "seeding" infact the eggs probably did survive and within a few days to weeks you'll see lil' white balls on your LR just after you turn on the lites.
