Are you sure you're not talking about nitrate levels of 30 and 10 ppm? Nitrite levels of 10ppm are so high they are unmeasurable by most kits.
Jden,
How old is the tank? If the tank is under 6mo old, this sort of thing is not at all uncommon. Measure at least daily and make sure they don't go any higher. It may be a good idea to keep about 15% of your water volume ready in new seawater to put in if it goes any higher. If it doesn't go any higher, keep watching and it should drop off on it's own.
