Anyone got a way to combat hair algae, I think any way I water change once a week reduced lights to 5hrs a day from 10 an feed lightly

Have you been overfeeding? Manually remove as much as you can with a toothbrush or pipe cleaner

green filamentous algae. it loves nutrients and light. reduce the nutrients to control it.

don't reduce the lights to less than 8 hours a day because the plants will suffer.
