Hi: I am a new member, so this is my first post. Are algae scrubbers useful in the commercial growing of chaetomorpha (chaeto) and ulva lettuce macro algaes. we use the south florida sun for the lighting. thanks Bart Jaffe

Welcome.

Scrubbers are optimized for nutrient removal, which is Light x AirWater Turbulence x Attachment. The attachment keeps the algal strands in-place in the rapid turbulence, and this removes the boundary layer of water from the algae which allows the most nutrient transfer (filtering). This is why a scrubber will out-compete chaeto in the same system.

However if the goal is just to grow chaeto or ulva, then you really don't need a scrubber; you can just swirl them around in the sun.
