You can't bring it down can you? I doubt it will be an issue once there is a demand for it but right now is there a problem with that?

No, you can't bring it down. It will probably be better once you have a demand for it. This is one of the reasons I switched away from IO which is 11 dKH out of the bucket. When I'm trying to keep 7-8 dKH a water change with 11 dKH can make quite a shift. I switched to H2Ocean and am happier that the alk is about 8.75 dKH (Elos) out of the bucket (first bucket I have tested...haven't double checked my numbers yet). I'm stoked I don't have to dose calcium, alkalinity, or magnesium with the H2Ocean, but the potassium is just as low as IO at ~250 ppm.
