Are there any recommended algae eaters?

Yes, there are. Most Loricariid (mostly plecos) catfish are Excellent, and a few Gyrinocheilus species (algae eaters) are good too. Keep in mind that the pleco you commonly in fish stores (Hypostomus plecostomus) can grow to 2 feet in length and you will need at least a 55 gallon aquarium to house them once they grow to adult size. For smaller aquariums, a bristlemouth pleco is usually recommended, since they grow to only 5 inches in length (they aren't as common as the Plecostomus species). Algea eaters don't grow as large, but when they are adults, they can be a little aggressive.

I disagree with this one, too. Plecos can grow to 6 feet in the wild, and just like any other animal (or fish), they have a genetic imperative to grow their full size. They will die once they run out of room to grow. That's probably why you say they grow to 2 feet. For a good algae eater, I'd recommend coryadoras, shrimp, otocinclus, and mystery snails. Making sure they'll work with your other fish, of course. Plecos put out more waste than they remove from the tank, so using one to control an algae problem will likely make the problem worse, not better. Cut down on your lighting and doing water changes more frequently will do more to reduce algae than a pleco would.
