• Dosing: 25 mL Excel, 15 ppm NO3, 1.8 ppm PO4, 1.25 tsp MgSO4, 4 tsp CaSO4
• NO3:PO4 Cumulative Dosing Ratio: 15:1.8 = 8.3

Notes:
50% water change:
25 mL Amquel+
25 mL Excel
1.25 tsp MgSO4
4 tsp CaSO4
2.5 tsp baking soda

Saw several juvenile shrimp while siphoning out the water during the water change. Even vacuumed out a shrimp shell, which I've never noticed before.

To try to combat the increase in green dust/green spot algae growth on the plants, I've reduced the light hours back again from 12 hours to 11 hours.
