FILTRATION DEVICE FOR SEAWATER AQUARIUM.

Abstract

Seawater filtration device for aquariums consisting of a cartridge filled with granules in the form of particles whose largest dimension does not exceed 0.5 cm, composed of a highly porous material, the volume of the alveoli being greater in percentage than the volume of the material itself, and the material comprising a component giving the granule a pH of approximately 8.3.

Description

The present invention relates to the filtration of seawater and in In particular, a seawater filtration system is essential for achieving biological balance in an aquarium. Saltwater aquariums present a major challenge to their biological equilibrium that freshwater aquariums do not. Indeed, in this type of aquarium, the water quickly becomes saturated with nitrites if care is not taken, and these nitrites are toxic to fish. It has been observed that a concentration exceeding 5 mg / l leads to fish death. Nitrites that accumulate in aquarium water cannot be avoided. They come primarily from fish waste, dead plants, and carcasses. fish, but also excess food. Nitrites are converted into nitrates by bacteria aerobic, the nitrates then serve as fertilizer for the plants. One way to eliminate nitrites is to introduce these bacteria into the aquarium water. Such a process presents the disadvantage of requiring almost daily maintenance. The applicant discovered that the mere presence of nitrites was insufficient to explain the toxicity in an aquarium. He observed that the pH value had an effect that compounded the effect of the nitrite concentration. Thus, if a filtration system introduced into the aquarium maintains a pH of 8.3, the nitrite toxicity is reduced, and significant increases in nitrite concentration are possible. in the aquarium do not have harmful effects on fish. The object of the invention is therefore a filtration device in the form of a cartridge to be installed in the seawater supply circuit of the aquarium, and which maintains the biological balance of the aquarium for a sufficiently long period of time, without having to worry about the concentration of salt in the aquarium.
