Lots of green algae in 3 month old tank. 0 nitrates, nitrites and phosphorus. Water changes or let it work itself out?

Can you tell us a little bit more about your tank?
Size?
Do you have a skimmer?
Do you have a sump?
What kind of flow?
What critters do you have?
What light scheme?
How long do you have your lights on?
Do you use RO/DI water?
That kind of information will enable the experts to give you some advice.
Regards,
Pat

75 gallon
On tank skimmer
Mechanical filtration
1 Rio Powerhead
3 T5 light strips
1 tang, puffer, sand sifting star, sea cucumber
We have cut back light to 4 hours a day
We started off with tap water, but since have done many water changes with RODI water.

This is what I see.
1. Not enough flow. You mention 1 powerhead but not the GPH. Based on my experience, even with the flow from the mechanical filtratation, it is not enough flow. I would suggest at minimum at least two maxi-jet 1200 power heads.
2. I would continue to use RO/DI water and nothing else.
3. You cut back the light that is good. I would keep it there for while.
4. Typically HOB skimmers just are not that great of a performer. I would try to improve that situation.
4. I would feed very little. You don't have a huge bio load but typically in my experience a lot of folks new to the hobby overfeed there tanks.
5. Read as much as you can, rudeBoy gave you a link.
6. Harvest as much of the algae as you can and do weekly water changes of at least 6 gallons per week. This equates to roughly 30% for a month.
If you take all those steps and read up on the causes and solutions, you will finally get ahead of this.
Good luck,
