The general consensus is that the test strips aren't very accurate. It will be better when you have the API test kit. Even though you show some nitrates, it looks like your tank is not fully cycled. How long has it been running? (Usually the presence of nitrates, with zero ammonia and zero nitrites indicates a completed cycle. But since you still have nitrites, something is amiss. Since you could have nitrates in your tap water, you should test your tap water too.
I think it's not a good idea to add any adsorbant like Nitro Zorb, Purigen etc. until after a tank has stabilized from the N2 cycle as this may inhibit the maturation of the beneficial bacteria colonies.
