Sounds awful lot like BBA (a red alga). Although it's called a red alga, it
can vary in color(black to light grey to reddish to slight green).
If it's slower growing and a nice deep forest green it may be a green alga,
Cladophora... it's not bad at all to get rid of.
The BBA will be silky and the green will be courser.

It really sounds like BBA. I've never seen green Cladophora attach to Gloss.
Suppose it could but I doubt it. Unless your gloss is really hurting but not
rotting yet. Is it growing on the edges of the leaves?

Not enough traces, add 5mls 2x a week. Don't add so much stuff to gravel.

Keep the CO2/KH in this range(KH 5 pH 6.6-6.8), Narrow range kits can get
this close for about 4-10$. Make sure the CO2 is well mixed.

You need NO3, 5-10ppm. Add KNO3. 1/4 teaspoon 2 x a week(this will add about
5-6ppm of NO3 per 1/4 teaspoon of KNO3, Grant's or Cooke's brands.
You sound like you have the light and substrate and CO2 going well.
Add more traces
Add K2SO4 about 1/2 teaspoon after water change
Add PO4 if your tap water has none(call and ask the water company)
Trim as much as you can off right now, then do a water change. Keep up on
the nutrients, CO2 and water changes. You can add 2-3 SAE's. Shrimps will
help once the algae is removed from coming back again. You may need to do
this procedure for 2-3 weeks before the tank gets going.
