How to Use

Add Fritz Complete directly to the aquarium or to the new water before performing a water change. Mix gently and the conditioner takes effect immediately.

• Standard dose: 1 mL per 10 US gallons (2.5 mL per 10 liters) of new water.
• Cap measurement: 1 capful is approximately 5 mL — treats 50 US gallons.
• Ammonia / nitrite emergencies: dose up to 5x the standard amount; repeat every 24 hours as needed until levels are safe.
• Always follow the dosing instructions printed on the bottle label.

What It Detoxifies

• Chlorine — neutralizes municipal tap water disinfectant on contact.
• Chloramine — breaks the chlorine-ammonia bond and detoxifies both halves.
• Ammonia (NH3 / NH4+) — converts free ammonia into a non-toxic form that beneficial bacteria can still consume.
• Nitrite (NO2-) — temporarily detoxifies nitrite during cycling and bacterial die-off.
• Nitrate (NO3-) — helps reduce nitrate stress between water changes.

FAQ

Can I use Fritz Complete in my reef tank?
Yes. Fritz Complete is safe for reef aquariums, including SPS, LPS, soft corals, and sensitive invertebrates when dosed as directed.

Will Fritz Complete affect my biological filter?
No. The detoxified ammonia is still available for nitrifying bacteria to consume, so your biological filtration continues to mature normally.

Can I overdose Fritz Complete during an ammonia spike?
You can safely dose up to 5x the standard amount during emergencies (cycling crashes, filter failure, ammonia or nitrite spikes). Always run a test before re-dosing.

How is Fritz Complete different from a basic dechlorinator?
Basic dechlorinators only neutralize chlorine. Fritz Complete also breaks chloramine, detoxifies ammonia and nitrite, and helps with nitrate — making it a true all-in-one conditioner.

Does it work on saltwater mix water?
Yes. Use Fritz Complete on tap water before mixing salt, or in any newly mixed saltwater that may contain residual chlorine or chloramine.
