DOSING PROTOCOL
How to dose safely
01
Test first.
Always measure your current concentration before dosing. Never dose blind. Use a reliable ICP test or a specific test kit for the element in question.
02
Split your dose.
Never add the full calculated dose at once. Split into 2–3 additions over 24–48 hours, especially when significantly below target.
03
Dose into flow.
Always add supplements into a high-flow area or your sump return section. Never dose directly onto corals or into a low-flow zone.
04
Retest and adjust.
Retest 24–48 hours after dosing to confirm uptake. Consumption varies by system — recalculate and adjust your schedule accordingly.
