The type of algae in a scrubber typically is turf or slime algae, it will grow naturally in the scrubber but not typically in a display
It does affect tank algae because this type of algae is more efficiently growing and is highly effective at pulling nutrients from water and growing at a high rate of speed.
All algae in the water will battle for the available nutrients, the idea is make the scrubber conditions so favorable that it’s grabbing them all up.
I had a scrubber and basketball of chaeto, and a tank full of hair algae. the scrubber algae outcompeted both and starved them out.
