  • Great Product - works instantly!!
Size: 8.45 oz
This fish water conditioner is a must-have. It quickly makes tap water safe, and I’ve noticed my fish are more active and healthy since I started using it. Super easy to dose with the built in measuring cap, and I love the peace of mind knowing my tank is safe.

  • Should have ordered Aquasafe Plus
Size: 8.45 oz
I condition the tap water I add in the weekly 25 percent water changes of my 29 and 60 gallon freshwater tanks. I bought this thinking it was a better deal than the Tetra AquaSafe Plus I've been using for years. Until I read the labels. This 8 ounce bottle will treat 240 gallons of water, while the same size bottle of Plus does more and will treat 500 gallons. After using this, I'll go back to buying the more concentrated Plus bottles. ... show more

  • Tetra water conditioner
Size: 8.45 oz
This is the only water conditioner I use for my fish tank. Does not cloud the water. The goldfish look nice and healty. It does a good job decontamination impurities. My water is clear. I use it each time I clean the aquarium. Its a good price. I order this all the time on Amazon for the price rather than the store. ... show more
