My main concern is about NO3, PO4 and GH levels. My tap water has very low KH, GH, NO3 and PO4 levels. All my tanks use pressurized CO2.

Plants are extremely adaptable. With PPS-Classic we saw what they look like in well managed levels. Then we found what plants need as a minimum requirement and put it into PPS-Pro. So here we have the minimum levels.

The maximum levels are controlled by plants uptake. However something can still go wrong and have an effect on nutrient accumulation. Here are some possible reasons, too few plants, unreasonable fish load, dissolving substrate, wrong lighting, wrong CO2, etc.
