Frequently the size UV
unit isn't large enough for the job. Even though the box says so.
Daphnia eat green algae in water. You could get a culture.
Are you feeding flake food? Flake can increase Phophates.
Try Hikari pelleted food.
Lowering light, adding plants which use up excess nutrients.
The light you have may be a color spectrum which isn't benefiting plant growth. Certain spectrum can increase algae.
Do you have a blue / night light you keep on? That can increase algae growth. Don't use it.
I would recommend checking the water, change and keep nitrates low, but also I would get Purigen. Asap. It helps get rid of silicates which diatoms use, not your specific issue, but also gets rid of organics, and is rechargeable.
Seachem also has Phosnet, Phosbond, and Phosguard, one which could help you remove phosphates. Forget which would be better.
If you end up using an algaecide it is not safe for invertebrates, please do not over dose, it can kill fish. .
