Finally Fix Trace Element Deficiencies Without Guesswork NO SUBSCRIPTIONS REQUIRED. KEEP YOUR PREFERRED ICP TESTING SOLUTION. Stop dosing bottles your reef tank doesn't need. Our Custom Reef Trace Solution is individually formulated using your ICP test results to replenish only the trace elements your aquarium is deficient in. Every bottle is made specifically for your reef, helping restore proper chemistry, improve coral coloration, accelerate growth, and maintain long-term stability. Most trace element systems add the same elements to every aquarium. The problem is every reef consumes trace elements differently. While one tank may need: - Iron - Manganese - Iodine Another tank may need: - Potassium - Strontium - Rubidium Adding elements your aquarium doesn't need can eventually create imbalances. Our ICP-based formula only includes the elements your aquarium actually requires. Doses up to 18 Major (macro), Minor & Trace Elements, including: - Barium - Boron - Bromine - Chromium - Cobalt - Copper - Fluoride - Iodine - Iron - Manganese - Molybdenum - Nickel - Potassium - Rubidium - Selenium - Strontium - Vanadium - Zinc DOSING INSTRUCTIONS Initial dose is designed to be dosed over a 30-day period, with the goal of reaching the target levels for each element in your ICP test. Elements come in just one or two 1000 milliliters bottles and should be dosed over a 30 day period for initial dosing. After initial month, suggested maintenance dosing can be administered over a 2-month period. Size​/​Option: 300 - 600 Gallons
