Seachem Prime 50ml Water Conditioner

Seachem Prime is a highly concentrated water conditioner for freshwater and marine aquariums that makes tap water safe in seconds. It removes chlorine and chloramine and binds toxic ammonia into a non‑toxic, biofilter‑ready form to protect fish during water changes and cycling. Prime also detoxifies nitrite and nitrate and chelates heavy metals commonly found in tap water, all without altering pH or affecting skimmers when used as directed.

Key benefits

• Complete protection: Removes chlorine and chloramine; detoxifies ammonia, nitrite, and nitrate to safeguard livestock.
• Biofilter friendly: Converts ammonia into a safe form that is processed by beneficial bacteria during cycling.
• Heavy metal control: Binds typical tap‑water metals to reduce stress and prevent toxicity.
• pH safe: Non‑acidic formula that won’t impact pH stability in freshwater, brackish, or marine systems.
• Highly concentrated: Powerful dosing lowers cost per use and reduces bottle waste.

Best for

• New tank setups and fish‑in cycling.
• Routine water changes with municipal tap water.
• Emergency response to ammonia or nitrite spikes.
• Transporting or quarantining fish where water quality can fluctuate.

How to use

• Dose as directed for total system volume during water changes or after testing shows ammonia/nitrite issues.
• In emergencies with elevated ammonia or nitrite, dose up to the maximum recommended frequency until parameters stabilise.
• Continue normal mechanical/biological filtration; Prime’s ammonia binder keeps fish safe while the biofilter removes waste.

Pro tips

• Pair with a reliable test kit and biological media to speed up cycling and maintain stable parameters.
• If using protein skimmers, adjust skimming temporarily after dosing in marine tanks.
• For high chloramine tap water, ensure full dose based on total tank volume, not just replacement volume, as needed.

Why choose Prime
Prime combines dechlorination with advanced detoxification of nitrogenous wastes and heavy metal binding in a single, concentrated formula. That versatility makes it a staple for both beginners and advanced aquarists looking for reliable water safety without pH swings.
