Lower the phosphate levels?

• pH:
• Temp:
• KH:
• GH:
• NH4:
• NO2:
• NO3:
• PO4:
• Iron:
• Dosing: 5 mL Flourish, 10 mL iron chelate (1 ppm)

Notes:
There seems to be more algae today. Possibly due to dosing of phosphates yesterday? Over the past day or so, it seemed to be declining until today. With less plant matter in the tank, it seems that it's much more important to keep a tighter rein on the level of phosphates, keeping it around 0.2-0.5 instead of 1.0.
