Dude.... My 150 took about 1.5 months to completely cycle. I also did a fish in cycle.
Still have all the original fish.
My ammonia reached as high as 8.0 and i kept it treated with ammo lock and huge waterchanges.
What do you have in there that's producing all that ammonia?
I'd do a 75% water change or at least enough to get a measurable ammount of ammonia. You should be able to cycle in a few weeks. Don't bother with the stability, that stuff is garbage.
Of course, I also have an UGF with 4 power heads, I "think" that drastically helped/helps my biofilter and the cycling process.
I never experienced water even nearly that cloudy.
How are you cleaning the filter?
That sure is some cloudy water. You should see some cloudiness but that seems excessive. Keep up on your water testing and frequent water changes. You'll see a bump in nitrItes, and then nitrAtes. They cycle is starting so hang in there!
