Ammonia is NH3 and ammonium is NH4. With biological filter, will be converted into NO2 and in-turn converted into NO3.

As mentioned in earlier post, guppies do need salt. However, not nececssary from water that we add. They can obtain salt from their food.

Question: What is the purpose of adding salt into guppy tank water?
