If it's the 8 drops of reagent A + 8 drops of reagent B, with nearly undecipherable colors of green, that's the test that I have. It measures total ammonia, which is both NH3 (toxic) and NH4 (not nearly as toxic).
Amquel or something like that will convert your NH3 to NH4. Unfortunately, your test will still detect the NH4.
Biospira is very similar to biozyme (the brown powder that got sent to you with your shipment). The biospira, biozyme, or bacteria in your LS & LR will eventually convert the NH4 to nitrite, then nitrate.
Look for obviously decaying sponges (if it peels off easily with the fingers...), and toss them. (My nose is pretty useless, so I can't use the stink test...)
