These are great replacement reagents for your saltwater fish tank. They work just as well as the original. I highly recommend them.

I have been using the checker for a good couple years. This is the second Refill ordered, and they are just as reliable and easy to use. The shipper got them to me fast and nicely packed....

Hanna reagents vary with Lot#, I bought these to compare my results with a different Lot#. I went from 22ppb with Lot# H025, to 6ppb with Lot# H030. I am sure these reagents are giving more accurate results. Specify Lot# H030 on your order.
