• Dosing: 1 tsp Equilibrium, 1.25 tsp MgSO4, 2.5 tsp CaCl2, 50 mL Excel, 15 ppm NO3, 1.8 ppm PO4
• NO3:PO4 Cumulative Dosing Ratio: 15:2.55 = 5.9

Notes:
65-70% water change:
1 tsp Equilibrium
1.25 tsp MgSO4
30 mL Amquel+
50 mL Excel
25 mL Melafix
3.5 tsp baking soda

Cleaned out AquaClear filter. Before siphoning out the water, I cleaned the lower half of the tank of the green dust algae. Then after draining the water, I cleaned the algae off the top half of the tank, above the water, in an attempt to see if this will reduce the levels of the green dust algae. I dosed the 2.5 tsp CaCl2 the next morning.

The Limnophila hippuroides has been growing in nice and big, as well as the stargrass. I dosed a tsp of Equilibrium in order to up the initial potassium a bit (+5 ppm, not including potassium from KNO3), since the stargrass was initially getting some black patches at the beginning of last week. Since I'm changing out more than half the water (close to 70%), I'm guessing that the potassium levels are too low immediately after the water change.
