What I've noticed with my bio pellets, is that once they get down to about a cup or 2 left in the reactor, they seem to last forever, with very little consumption. Last time, before I filled the reactor again, I went almost 2 years without adding any. And all that time, nitrates remained at zero.
I actually disconnected the reactor for a few months, and then watched my nitrates gradually climb. So the pellets were obviously still working, even with very low consumption.
My concern with the npx pellets might be that if the consumption is too slow, then there wouldn't be enough GFO released to bring down the phosphates.
