Marine Basic:This kit combines the Marine pH & Alkalinity, Ammonia and Nitrite & Nitrate kits into one kit. Each kit runs 75 tests. I maintain: pH=8.2 Alkalinity=8dKH Ammonia=0 Nitrite=0 Nitrate=5 mg/L

Reef Special: This kit combines the Phosphate, Silicate, and Iodine/Iodide kits into one kit. Each kit runs 75 tests. I maintain: Phosphate=0.01mg/L Silicates=0 Iodine=0.03mg/L

Calcium: This kit measures all types of calcium, including gluconate calcium. The method is based on specific titration with a unique indicator. Measures in increments of 5 mg/L. Runs 150 tests. I maintain: Calcium=475mg/L

Strontium:This kit measures strontium by first seperating the strontium in the sample by a chemical precipitation and filtration, followed by a sensitive titration in 0.5 mg/L increments. Runs 50 tests. I maintain: Strontium=10mg/L

Magnesium,Carbonate/Borate/Total Alkalinity: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 run 75 tests. I maintain: Magnesium=1400mg/L
