Trying out the UV sterilizer so far

• pH: 6.7
• Temp: 78
• KH: 5.5
• GH: 6
• NH4:
• NO2:
• NO3: 10-20
• PO4: 0.35
• Iron:
• Dosing: 10 mL Flourish, 1 ppm iron chelate, 1.25 ppm KNO3, 1.4 ppm KH2PO4
• NO3:PO4 Cumulative Dosing Ratio: 16.25:2.6 = 6.25

Notes:
There has been a slight almost bluish haze since the water change and addition of the UV sterilizer yesterday. I switched off the UV sterilizer today, and within a couple hours, the bluish haze cleared away. Perhaps the haze is from dead/dying free floating algae, or perhaps something is being oxidized and precipitating out, I don't know. Perhaps there is even some reaction with the Melafix. The instructions for Melafix recommend that the UV sterilizer not be run when using the Melafix.
