Accurate and easy to test By Tek on 11/25/2014Tek would recommend this product to a friendAccurate and quick test. Great value refills as opposed to buying new kits each time.
Got very different readings with new refill By Joe on 8/27/2013Joe would recommend this product to a friendI just got the refill on the Ca test. However, the original kit gave a Ca reading of 415 ppm, which seemed too low give Alk levels and Ca reactor drip rate. The new reagents, tested at the same time, gave a Ca value of 575 ppm (measured twice). That's a huge difference from the same kit.
The original kit was about 1.5 years old, so my only guess is that the reagents go bad in a year or less.
Excellent Product By TheReefSpot on 5/27/2013TheReefSpot would recommend this product to a friendI have been using Red Sea test kits for a long time. It is so nice to be able to buy a refill reagent instead of purchasing the entire test kit over and over. Doesn't come with the syringe toppers, which have a tendency to split or break over time, but it does exactly what it is supposed to. Provide results.
Good Value By Jimmy on 5/4/2012Jimmy would recommend this product to a friendI commend Red Sea for selling refills rather than just complete kits. I have countless test tubes from previous purchases. Good to use your money to what you really need....reagents.
