Royal Nature Ammonia Professional Test Kit
Ammonia - NH3 can appear in two forms in water
1. Free ammonia
2. Ammonium ion NH4
NH3 + H = NH4
Ammonia is considered as ion with high toxicity and thus is important to make sure that we don’t have high levels of Ammonia in our tank. The NH3/NH4 ions are strongly depending on PH levels. The lower PH is - the more NH4 we get. (NH4 is not as toxic as NH3) in PH of 8.0 - 8.4, NH3 will be dominant.
Royal Ammonia test kit will measure both: NH3 and NH4 levels in your tank.
There are few sources of Ammonia in reef tanks:
