Dosing Formula:
Nitrate:
2ml per 100L = 0.5 mg/L increase
Phosphate:
2ml per 100L = 0.05 mg/L increase
Tank Type Guidelines:
SPS Dominant:
Ultra-low nutrient system for SPS corals
Mixed Reef:
Balanced system for mixed coral types
Fish Only:
Higher nutrient tolerance for fish-only systems
Dosing Tips:
Never exceed the maximum daily dose recommendation
Test parameters regularly during dosing period
Maintain proper N:P ratio for optimal coral health
Adjust feeding and maintenance based on results
