A common routine supplies macronutrients three times per week and trace nutrients three times per week, with a roughly 50% weekly water change to help control accumulation. Adjust the routine for actual water volume, plant growth, lighting, CO₂ and nutrients already in your water.\u003c\/p\u003e\n\u003cp\u003eThe supplied jar weights are package quantities, not a mixing recipe or a dose. Bottle capacity and pump size alone do not establish how much fertilizer your aquarium needs.\u003c\/p\u003e\n\u003ch2\u003ePlan your dose\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/thewetleaf.ca\/pages\/fertilizer-calculator\" style=\"display:inline-block;padding:12px 20px;border:1px solid #708090;border-radius:6px;background-color:#708090;color:#fff;text-decoration:none;font-weight:600\"\u003eOpen our fertilizer dosing calculator\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eUse the calculator to examine nutrient additions for your actual water volume.

Only use verified product analyses and a verified recipe when preparing stock solutions; no universal bottle recipe or pumps-per-tank dose is specified for this kit.\u003c\/p\u003e\n\u003cp\u003eCSM+B formulas can differ. Match the guaranteed analysis on the supplied jar when planning doses. This mix contains copper; account for all copper sources when dosing aquariums with shrimp or other invertebrates.\u003c\/p\u003e\n\u003ch2\u003eStorage and handling\u003c\/h2\u003e\n\u003cp\u003eKeep the jars tightly closed in a cool, dry place, out of reach of children and pets. Potassium nitrate is an oxidizer and may intensify fire: keep it away from heat, flames and combustible materials. Avoid breathing dust and use protective gloves and eye protection when handling.
