What do brown algae eat?
If you are wanting to get rid of it, the best way is to use an algae eater, such as a plecostomus or Otoclincis catfish. (Contrary to popular belief, snails are NOT good algae eaters, as they only snack on the top layer, and will only do that if no other food is available). Another option is to perform daily partial-water changes and scrub all of the algae so it does not take hold on the walls and decorations of the aquarium. The daily water changes will remove the phosphates and make survival difficult. More live plants is also effective, as it causes the algae to fight for nutrients.
