Hanna HI772-26 Alkalinity Reagents, 25 ct. for use with Hanna HI755 and HI772 Marine Alkalinity Checkers

I'm very impressed with Hanna. these reagants are sealed tight on the outside PLUS a plastic seal on the inside. You can tell they are not made in China.

I will never use another test kit. The reagent price makes it affordable to test more regularly to ensure steady water parameters. Best price I have found!

Say Goodbye to Your Test Kits.

Purchased the calcium, alkalinity and phosphate checkers, wish they made one for nitrate and magnesium so I could say goodbye to the rest of my test kits.

great buy

I purchased an extra reagent vial with my new Hanna checker kit. I was pleased to find the expiration date was over a year out.

Works great. The extra pipepets make it worth the buy.
