Seachem Prime

Seachem Prime is an essential water conditioner for both freshwater and saltwater aquariums. This concentrated formula neutralises chlorine and chloramine while binding ammonia, nitrite, and nitrate to render them harmless—giving your biofilter time to process them naturally. It detoxifies heavy metals commonly found in tap water and won't alter pH or over-activate protein skimmers, making it ideal for reef setups. Apply at initial setup and with every water change to maintain a safe, stable environment for your livestock.
