Very few of these even support good growths. I have yet to see a hair algae laiden, underskimmed reef show a good coralline growth rate. That is based on visiting over 30 reef dealers in southern cal. Some of these were marginal reef supporters. They do claim to make a mean skimmer.
Black acrylic is chemically and texturally somewhat different than clear.
Dave O'Brien was recently told by an aquarium manufacturer that the black acrylic on a particular tank had to be thicker since it wasn't as strong as clear. I don't know if that's a good explanation or not, but it seems plausible. It has all sorts of info on chemical and physical properties. The polymer structure of acrylic must be micro porous. That may be why the coraline algae has an easier time attaching to the acrylic than glass.
