Product details
Tetra AquaSafe Plus, treats 2 times the water of regular AquaSafe and works instantly to make tap water safe for fish in freshwater and marine aquariums. This BioExtract formula contains natural biopolymers to support the development of beneficial filter bacteria for healthy and clear water.

Unique colloid ingredients protect your fish’s delicate gills and membranes. Use with freshwater or marine fish. Add 1 teaspoon (5 mL) for every 10 gallons of aquarium water. Top of bottle cap can be used for measuring – fill to inner ring-line to treat 10 gallons or use one full capful for 20 gallons. Make sure that replacement water is the same temperature as water in aquarium. Tetra AquaSafe Plus is not a medication and is not intended to be a substitute for any medication.

Happy Fish
Happy fish...happy life! My little glo fish are two years old and swimming strong! I use this when I clean their tank to make sure the water and plants are safe from soap and chorine. I'm grateful to see their cute faces gathering for breakfast...alive and well.
