If your nitrates are zero right now when you test then do this (other post was edited)

Rinse test tube & cap in tank water

Fill to 5ml

Shake Nitrate bottle 1 for 30 seconds - add drops to tube

Cap tube & pick up bottle 2 - simultaneously shake bottle 2 and the test tube for 30 full seconds

Uncap test tube & add drops of bottle 2

Cap & shake for a full minute

Set aside & wait 5 minutes - what colour is it?
 
I also have a canister filter hooked up, but I don't have carbon or ammo chips in it. Just bio stones and some of that cotton looking stuff.
 
The cartridges that come with many HOBs contain carbon and/or ammo chip crap.

I would suggest that you use some sponge & some biomax in the penguin instead so you rid yourself of inserts.
 
Ok. I did all three again. Ammonia is yellow, nitrates are yellow, nitrites are purple (looks like 2.0 ppm).
