Review on Hanna Freshwater Alkalinity Checker® Reagents by Glenda Vollan

Revainrating 5 out of 5

This is a good product

I have a 300 gallon aquarium with a pH of 6.8, 3 dGH and 3 dKH . I adjust the KN with a pump. This adjusts the pH and CO2. For this you need to know + -3ppm. And this product has it all.

Pros
  • Marked with an expiry date and lot number for traceability
Cons
  • I don't really like it, it's ok
