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.

The best way to keep your aquarium healthy
Size: 8.45 oz
Use this to fill your jugs a few days early and your fish can be thriving like ours. A very affordable option to ensure your water stays clear, smells like a dream, and keeps your fish healthy.

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
