For a new tank, you will not need anything for algae control for quite some time. IME, the best for eating algae are otos or Siamese Algae Eaters, but it depends what kind of algae you have....which is why you might want to wait until your tank is established and you know what kind of algae you have. If you do get 'algae eaters' right away, make sure you feed them algae wafers and veggies -- even in a long-established tank with lots of algae, they will quickly eat it all, and as they are herbivores will starve to death without veggie/algae based food.
