An algae scrubber allows algae to grow, but the algae grow inside the filter instead of in the aquarium or pond. This removes excess nutrients (scrubs the water), diminishing nuisance algae in the aquarium or pond . Nuisance algae in the aquarium or pond are not to be confused with the desired algae in the algae scrubber filter itself.
Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a] Staghorn algae of the genus Compsopogon may exist on aquarium substrates and can be epiphytic on slow-growing plants. [2] It can form branched, whitish-green strands up to six inches ...
Aquariums are usually much more densely stocked with fish than the natural environment. This increases the amount of ammonia produced in the relatively small volume of the aquarium. The bacteria responsible for breaking down the ammonia by converting it to nitrite, Nitrosomonas , colonize the surface of any objects inside the aquarium.
Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems.Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and ...
Due to the artificially limited volume of water and high concentration of fish in most aquarium tanks, communicable diseases often affect most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental fish in a tank.
In fishkeeping, a refugium is an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply. It is a separate sump , connected to the main show tank. [ 1 ] It is a " refugium " in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic ...
Traditionally, when fish would exhibit dropsy, it was advised to “destroy” it. [2] However recently, it is recommended to “bathe” the fish in water that has aquarium or epsom salts dissolved in it, as the process of osmosis may help relieve pressure on the fish. Antibiotics may destroy or weaken the pathogen if it is bacterial so that ...
Fish require oxygen to metabolize food and grow, as do bacteria communities in the biofilter. Dissolved oxygen levels can be increased through two methods, aeration and oxygenation . In aeration air is pumped through an air stone or similar device that creates small bubbles in the water column, this results in a high surface area where oxygen ...
