what are your other levels at and what were the levels the last time you tested?
Hmmm.
I haven't used that product, but I believe if you are not feeding it an ammonia source, the bacteria die off.
Since you added the shrimp, what did your ammonia level get to at its highest point?
I would let us know those three chemical levels currently, possibly done because you added the bottle bacteria, or still ammonia present due to the shrimp.
Here is a way to test; (after posting the levels)
Dose pure ammonia to 2-3ppt.
(Approximately 1drop /gallon).
Test in 24hrs.
If its zero ammonia, do it again.
If still 0, then your cycled.
Temp 79.5
Salinity 1.024
Ammonia 4 ppm
Nitrite 2 ppm
Nitrate 40 ppm
