Tetra AquaSafe Plus Aquarium Water Conditioner & Dechlorinator, 33.8 oz

Instant, safe water conditioning for your tank

Tetra AquaSafe Plus is designed to make tap water safe for fish in both freshwater and marine aquariums. Its BioExtract formula uses natural biopolymers to support the development of beneficial filter bacteria, contributing to healthier and clearer water. The formula also includes ingredients that form a slime coat to help protect fish and support gentle healing of minor abrasions, while colloid ingredients help shield gills and membranes from irritation. This combination aims to create a more stable environment without being a medication.

What you’ll notice in daily use is a more approachable setup routine, clearer water during and after changes, and a calmer, more comfortable environment for your aquatic residents. The conditioner is intended for use in a range of scenarios, including new tank setup, monthly partial water changes, and evaporation replacements, making it a versatile addition to many hobbyists’ routines.

Real-world use and dosing guidance

Follow the simple dosing directions to balance your tank's water chemistry. For every 10 gallons of water, add 1 teaspoon (5 mL). The cap doubles as a measuring cup—fill to the inner ring-line to treat 10 gallons, or use a full capful for 20 gallons. Always ensure replacement water matches the tank’s temperature to minimize stress during water changes. Note that AquaSafe Plus is not a medication and should not replace prescribed treatments.
