Excellent Product By TheReefSpot on 5/28/13TheReefSpot 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 5/4/12Jimmy 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.
