Ah, mostly I was confused on the difference of using reduced amounts of GFO or not. Been using much less than the recommended amount at first but since the reactor outputs 0 anyhow. So I'm unclear of what's the point of adding more gfo at a time down the road, since the capacity to reduce PO4 can't really be any better than it is - except that "more gfo" should also mean "replace less often" .. but I'm kind of thinking it works out the same either way? Is the difference of 1 cup in the reactor, and 2 cups in the reactor .. the same as the difference of "replace every week" or "replace every 2 weeks"? Sorry I'm not a very good communicator so I have no idea if this makes sense or not.

I just used to test my PO4 every couple of weeks, if it stayed low all was good, if it went up a little, I'd change out the PO4. Currently I change it out about every 6 weeks or so whether it needs it or not (stopped testing). Most of my PO4 is tied up in caulerpa anyways

I just removed my phosphate media reactor completely. It had been months since I changed the media, so it clearly wasn't doing anything and the tank is doing great.
