General Dosing Guidelines
The standard Masterline dosing recommendation is 1 mL per 30 liters of aquarium water per day for most products. This can be split into daily doses or applied weekly. After water changes exceeding 50%, apply triple the standard dose. Avoid UV lamps when dosing; if necessary, double the dose. Actual requirements depend on plant mass, lighting intensity, CO₂ injection, and fish load.
