Product details
Seachem Prime 50mL (434) is a concentrated water conditioner for freshwater and saltwater aquariums. It is used to neutralize harmful chemicals commonly found in tap water—such as chlorine and chloramine—and helps reduce toxicity from nitrogen compounds by detoxifying ammonia, nitrites and nitrates. It also helps support fish health by contributing to a natural slime coat and conditioning the water with essential ions. Prime is commonly used during tank cycling and whenever you add or replace water to support stability while you maintain biological filtration.
Features:
- Deconditions tap water by removing chlorine and chloramine for freshwater and saltwater aquariums
- Detoxifies ammonia, nitrite, and nitrate so they are rendered non-toxic while the biofilter works
- Helps bind or address heavy metals typically present in tap water at normal levels
- Supports fish with a slime-coat–friendly conditioner effect
- Concentrated formula designed for efficient dosing
- Non-acidic so it is intended not to impact delicate pH balances
