I personally prefer sand because its easier to keep clean. I have heard that pool filter sand works, and so does blasting sand. I would stay away from playground sand though, its excessively dirty and can take forever to clean.
Plecos can eat algae, but that shouldn't be all that you feed them. Plecos are good cleaners when young, but they turn into lazy poop machines as they get older lol!
