Troughs grow algae, not collect moss. Moss can't live under water.
All stock tanks, regardless of their make and material, grow algae. Horses slobber in the water, they throw organic material (feed, hay, grass) in the trough, and other things happen that encourages the growth of algae.
There are various ways of minimizing algae in water troughs but I don't think you can ever get rid of it completely, and certainly not forever. There also isn't a type of material that's 'less grippy' for algae.
I have Rubbermaid troughs. I like that they're much lighter and easier to move when empty, as opposed to metal troughs.
You want the truth? You can't HANDLE the truth!
