What level of phosphate is typical in a NPT?
It seems that the potting mix I am using has a lot of phosphate in it. The level in both the tanks I measured is around 3ppm. One of the tanks I just set up yesterday, the other has been running for months and had a lot of water changes in the first couple of months.
I believe this level is higher than advisable for a planted tank. But then fish and plants both seem fine in the established tank, and while I have some hair algae growing it's not taking over the tank or anything.
Does anyone know what level of phosphate is usual or advisable in a NPT?
