Yes, I would recommend this.

Reliable Product

Pros: ease of use, consistent ly accurate results

Cons: not really a con, but be patient on the "true" color change as described in the directions.

I have found the NYOS Calcium test kit to be consistent and accurate through many applications. IMO, the NYOS Calcium test kit and the Red Sea Calcium Pro Test kit are the two best on the market today. The NYOS is a little easier to use than the Red Sea test kit, but I use both every so often as a sanity check. I've tried Salifert and Elos and others and found them unreliable to some extent.. The NYOS product is my go to for calcium.
