I am writing this because I really like Hanna checks for my reef tank

I am writing this because I really like Hanna checks for my reef tank. I believe them to be accurate and rely on the results for my reef tank. Having said that, this test will NOT work for a reef aquarium!

Pros
  • Industrial & Scientific
Cons
  • There are new competitors

The meter is easy to use and accurate

The meter is easy to use and accurate. The only difficulty is fitting the entire pouch of reagent paper into the vial. It took me a few tries to get it right. It's also a little difficult to remove the battery cover to insert the battery. I had to carefully pry off the lid with a knife.

Pros
  • Test, measure and test
Cons
  • weak
