Recieved two bottles of A for the calcium test, how do I get a bottle of B?

Some people I swear, you got a bottle of A and a bottle of B.

How accurate is this kit? Planning on switching from Salifert as I think this will reduce my costs some, seems easier to use with hand tool?

According to the kit, the Calcium is +/- 5ppm, KH is +/- 0.05 meg/l and the Mg is +/-20 PPM. Ive only had it a short time but I have found it to be accurate based on my tests. I have verified dKH was very close to my Hanna tester. I have only used 1 salifert kit and I can tell you the Titrator handle makes adding the titration fluid easy and quick. Overall it makes the tests much easier to perform.

Is there a refill kit for these tests with just the Titrant’s and Reagent’s?

Not with the one I bought. But you can buy them with the refill kit or get them at Petco.

by other reviews, do these kits still contain the recalled calcium reagant? These are the faulty batch numbers. Thanks

Stamped on the label of Calcium Reagent B, and compare it to the list of faulty batches: 1993, 2003, 2013, 2023, 2033, 2043, 2053, 2063, 2073, 2083, 2093, 2103, 2113, 2123, 2133.Those were the only batch's that were faulty.

RED SEA REEF TEST KIT - VERy GOOD 100% Excelent

RED SEA very good product. At first a little reading and understanding as their use. NO is very easy ... you need patience and understanding. For l amount of criticism I've read: many people do not know how to use or simply not read the instructions. Already today: after almost five reading TEST of each: excellent and very good .. I checked with other TEST (API SEACHEM) and are very even. The material is very good briefcase; Sturdy appropriate, arrived quickly, very good price relationship. It is a very good product for REEF aquarium. If you are a keen aquarist should have the equipment on hand. I have NO complaints
