Back from vacation

• NO2:
• NO3: almost 0 after water change
• PO4: ~2
• Iron:
• Dosing: 5 ml Flourish, 2 tsp CaSO4, 1 tsp MgSo4, 15 ppm NO3, 1.8 ppm PO4
• NO3:PO4 Cumulative Dosing Ratio: 15:1.8 = 8.3

Notes:
Back after 2 week vacation, and the tank looked like a jungle. Someone had come in every other day to add the following to the tank:
5 ml flourish
20 ml Excel
7.5 ppm NO3
1 ppm PO4

When I came back, there surprisingly was a lot of brown algae.

I cleaned the tank out with a 50% water change:
35 ml Excel
1 tsp MgSO4
2 tsp CaSo4
20 ml Amquel+
2.5 tsp baking soda

Later:
5 ml Flourish
15 ppm NO3
1.8 ppm PO4

The tank doesn't look so great, it will probably take another several weeks to get it back into shape again.
