I Have used a turf scrubber for the last several years. The pic is of the unit when new. The acrylic body was broken on mine so it now sits in a glass body. The other pic is of the turf screen in the scrubber, which by the way grows turf algae not hair algae. :razz: Mostly red and green turf.
It is fed by a large powerhead from the sump and dumps direct into the tank. Over the years its been on several different tanks. I have usually run a large skimmer along with it. I can feed very heavy and never have any ammonia, nitrite, nitrate, phosphate. However I wonder about its ability to function as a complete filter alone on the size it was rated for, which was
250g. Perhaps its because until recently, I never had a good turf algae growth. To hard to get the seeded screen up here, so I never bothered.
Its lit with a pair of 55w power compacts, run during the night. I scrape the screen once or twice/week, depending on how ambitious I am.
