Change is slow.Update: I kept the canister filter on there for a little over a week, stirring it like mentioned and water changes when I could. I also put a powerhead in the sump to add some aeration down there. Not a lick of change. However, I now have a thin green film starting on the glass and bits of cyano growing on my rock. I can't decide if I am excited that I have something other than dinos to look at or sad that I have another "big one". Ugghhh
