They work well by adding a lot more light in the ATS vs the aquarium.
If you add lots of light to both locations, they are the same then.
So they do not eliminate algae per se.
They remove nutrients, but plant filters/emergent plants are FAR more effective and a simpler device. Reef folks have macro algae, the grasses and trees do not remove like the FW emergent plants.
Floating water sprite etc, or a peace lily in a wet/dry section will out perform any algae filter with less energy.
"Hydrophyte" has several simple hand on or suction cup planters that would do the job if you want to keep it simple.
