Wow growing a garden in there? LOL
Do what you can to siphon as much of the hair out of your tank, these rocks seem loaded with phosphates, probably due to die off in shipping. You will be ok just this sort of thing is taking longer than normal doesn't happen to everyone but at times it happens you can gain on this, siphon as much of that green stuff as you can. I'm thinking after a through cleaning your traits should go even lower then it may bounce back up a few days later but at that point I think it should be time to start adding in small amounts, getting life in there like a fish will speed up the cycle some, I wouldn't stock heavy just yet though, maybe a fish like a hippo tang to help graze & very little feeding until you see it grazing & your rocks clears up better. I would suggest after your do the change test & then test again a few days later if it is good for fish then I would put some life in there & start wc's & cleaning steady weekly vigently until it clears up.
