Thanks @Zeus. I may fiddle with the location of my hob filter (but when I moved it, it bent my plants that were directly under it because of the flow ... maybe canister is the way to go (sumps not an option). I could then position the diffuser under the intake and get better dissolution —> I am realizing now that my left side hardscape is horrible for flow ... it is basically all rocks that I needed to add at the time to weigh down the driftwood.
I also notice the concentration on the surface varies as my tank evaporates ...
