First driveway with new equipment ... not happy!

Hi Guys

So I purchased my first good pressure washer this week, a Pressure Pro belt drive 4gpm 4000 psi with 18" surface cleaner. I am a little disappointed with a job and wondered what you guys would have done in this situation, it was a job for possibly my worse ever customer......MY WIFE!

I used a downstream injector with chlorine before I washed the driveway, its a 25 year old driveway and its lost its top smooth surface. Its not been cleaned for about 5 years or more and lots of algae came off (I am in central Florida) but it left lots of black spots, I used a yellow tip straight on it and it didn't budge, poured straight chlorine on it too still nothing! I have attached a few photos, anyone came across this before, should I be using a soap or something else?
