Well, keep in mind I am totally jaded after fighting this for a several months.
Allot of people shoot for .05 or even .02. So that means that you are running 10x higher or even more than some shoot for.
Because of recent experience, if it were me, I would acid bathe the rocks. Extreme I know and sure won't help your tank cycle, but it is probably what I would do. Others should chime in.
No matter what you decide, at least you are going in with eyes wide open! Good luck!!
