This makes no sense, phosphate went up, DKH went down.

The alk change is probably just test kit variability, but expect a steady downward trend and don't worry about trying to understand tiny ups and downs. The GFO may also accelerate some precipitation of calcium carbonate on or near it.

How are you measure alkalinity and phospahte?
