Red Sea Ammonia test kit with 45 tests

Accurate measurement of Ammonia (NH3 & NH4 + ion) - An essential test for new and established aquariums

Ammonia, which is toxic for fish, is regularly introduced into the aquarium by fish waste. An established, functioning biological filter converts the ammonia to nitrite and thereafter to nitrate, which are less harmful.

Regular testing for ammonia will provide confirmation that the biological filter is functioning correctly.
