Turn off the lights, wrap the towel in a blanket to block off any light, gravel vacuum, water change.

How long would this take....roughly?

I don't know, i am assuming new tank, oodles of light, used tap water in beginning, overfeeding a bit, i sneezed the wrong way......beats me. That's why i am here asking for help.

The reason why I ask is that it will never go away unless the root causes are looked at.

Does this tank have any sunshine?
How long is your photoperiod? (what lights?)
What sort of substrate do you have?
How much do you feed?
What is your filter?
How much for plant do you have...and what kind of plants?
How often and how much do you do for a water change?
Do you have any other algae growing? GSA, BBA etc.
Do you vacuum your gravel?

1. sunlight: yes some light in morning, but i have blocked out the sun hitting the tank with some background taped to the side(where sun hits).
2. photo period: 830-9pm 12-12.5 hours, 2x24watt 10k T5HO
3. substrate:black flourite
4. filter: rena xp2
5. plants: HC (hemianthus callitrichoides), dwarf 4 leaf clover(marsilea hirsuta)
6. water changes: 30% every 2 weeks. (~10gallons)
7. no other algae growing
8. I only vacume the very top bit, i do not push the siphon hose down into the substrate (as it disturbs my plants).
Does this help?

I've got a similar tank.

I found reducing the photoperiod cleared it up in about 2 weeks.

I currently have it at 5 hours / day. Any more and I get too much algae in one form or another.

Livestock: 5 guppies, 3 zebra snails.

Suspended algae in my reef was gone after a 100% block out of light for 3 full days. 100% dark! Dont even peek. Than a large water change. Idk what caused it but the black out worked and never had a problem since.
