Trouble using the Seachem nitrate test

• pH:
• Temp:
• KH:
• GH:
• NH4:
• NO2:
• NO3: 5
• PO4: 1.5
• Iron:
• Dosing: 5 mL Flourish, 0.5 ppm iron chelate, 7.5 ppm NO3, 0.4 ppm PO4, 2 tsp Equilibrium
• NO3:PO4 Cumulative Dosing Ratio: 18.5:2.4 = 7.7 (estimate 1 ppm nitrates, 1 ppm phosphates before dosing at water change during weekend)

Notes:
I had trouble using the new SeaChem nitrate test. The colors were difficult to match up, and I kept getting different readings when I retested several times.

The stargrass was showing black patches on the leaves, so I added 2 more tsp of Equilibrium to see if that would fix the patches. The added Equilibrium should raise the GH about a degree.

The flower bud growing from the anubias nana has opened up today, looking like a cala lilly. Another flower bud has also sprouted up. It looks like having higher levels of phosphates (2 ppm or more) encourages the nana to sprout flowers.
