Regime
Lean Dosing
Philosophy
Lean Dosing assumes many tanks already have sufficient nutrients from bioload and substrate. Only micronutrients are dosed; macros are added individually only when tests confirm a need.
Recommended nutrient targets
| Parameter | mg/L |
|---|---|
| N (NO₃) | 5 |
| P (PO₄) | 0.5 |
| K | 10 |
| Fe | 0.1 |
| Mg | 2 |
| Ca | 10 |
| B | 0.005 |
| Mn | 0.05 |
| Zn | 0.005 |
| Cu | 0.002 |
| Mo | 0.001 |
Dosing frequency
2-3x/week micros only, macros on demand from tests
Water change
20-30% weekly
CO₂
Not necessary
Light
Low (15-30 PAR)
