Hair Algae in 30g AIO Refugium

[Justen]

I have a lot of hair algae in my chamber which I use as an refugium to grow chaeto. The chaeto grows very nicely but so as hair algae. It becomes very thick in less than a week everytime I clean it. My main display has little to no algae though. Just some on the glass. I run the light for my chaeto at off hours and started running it for even less. About 8 hours instead of 12 hours but I am still seeing lots of hair algae. I have a mini pump in there to help improve the flow but I doesn't work to well and the algae just grows on the pump. How can I reduce the algae and grow chaeto at the same time.

Livestock isn't too heavy, I have 2 clownfish and 2 cleaner shrimps.

The chambers go Filter>Protein Skimmer>Refugium>Pump

I use the same light as in this video

Manual removal as you are then exporting nutrients or some sort of clean up crew that eats gha.
