Well that's not it.

Take a good look at it again.
This will never hurt.Check from the AM to the PM for variation.

Something else happened in there.You over pruned perhaps or did
something.Once you tip that, getting rid of it is a tough deal.
GW just does not appear out of the blue, I never once had it and I trashed
tanks.
I had to add too many fish or add NH4 to get it to bloom. But with good CO2
that was the trick. Light was 4-6w/gal range so high light was not it
either. 

The algae you had on the glass is a totally different species of algae than
GW.

Well, you can forget about the media thing from the sounds of it.
I think the issue is one of running the Diatom for the next couple of days.
Don't just run the Diatom for a few hours, let it go for a couple of days.

Do a big old water change, run the diatom for 2-3 days at least. Rev the
CO2.
Leave the tank alone and see if the GW comes back. You canl take it to the
next level, UV etc later perhaps if these things don't work you already
have.
