Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United ...
Species may be unintentionally disseminated through spores and fragments that hitchhike on ornamental fish and plants purchased from aquarium suppliers. [1] Algae is typically considered a nuisance and subject to removal through the use of algicides and the release of algae eaters. However, total elimination of algae is considered unlikely in a ...

[15] When people manage algae blooms in fish ponds , it is recommended that treatments be staggered to avoid too much algae dying at once, which may result in a large drop in oxygen content.
Because the red algae-eater is effective at controlling tank algae, many aquarists like to place them in heavily planted tanks with strong lighting to prevent the growth of algae. Unlike other aquarium algae eater fishes, the red algae-eater is valued for its ability to eat red algae (particularly Audouinella). The fish, however, is an ...
