Four kits in one! Tests for magnesium through a titration based procedure in increments of 12.5 mg/L. Tests for carbonate alkalinity, borate alkalintiy and total alkalinity in 0.1 meq/L resolution through a titration based procedure. The kit resolves borate from carbonate and, along with magnesium, this presents a clear picture of the tank's buffering capacity as well as a very reliable determination of the critical carbonate content required for coral and coraline growth. Each kits can perform 75 determinations for each test... Read More

The first and only 10 minute strontium test! The test involves separation of strontium from the sample by a highly selective extraction technique, followed by a sensitive titration in 0.5 mg/L increments. Each kit runs 50 tests... Read More
