I have a 55 gallon planted tank, dosing dry ferts using EI, pressurized CO2, 2.3wpg of lighting. I have been testing my phosphate levels the past couple of weeks, and after each 50% water change my levels are just under 1.0ppm, but as the week goes on, even without dosing any phosphate this week, my levels have risen to nearly 2.0ppm as of this evening. What could be causing me to get such high phosphate readings even when I am not dosing any, and is this a bad thing? It hasn't ever went above 2.0ppm by the end of the week, but I'd like to try and keep it closer to 1.0ppm by the end of the week if possible.
I have tested my tap water several times and I see no traces (or extremely minimal traces) of phosphates in it, so I'm not sure where else I would be getting it from. Any suggestions or ideas?
