If large public aquarium lacks fewer elements, the closer the shares of each element are to the natural conditions, the less protection operations will be carried out. Otherwise, there will be more protection work to be done.
Method 1: Set up a "bare tank" for pure fish culture only with submerged biochemical filter. This tank should be full in appreciation. Under normal circumstances, the density of fed fish will often reach the upper limit that the filter of the fish tank can bear. In this way, the proportion of bacteria and fish will be unbalanced. If this kind of fish tank is protected, besides feeding the fish every day, it is also necessary to regularly suck out the residual bait and excrement at the bottom of the fish tank, and frequently change the water, so as to better dilute the harmful waste in the fish tank. When the water temperature is high, air pump is required to pump air. This requires detailed decision-making plan according to the fish species.
Method 2: Set up a "aquatic macrophyte large appreciation fish tank" with biochemical filters, bottom sand, a large number of aquatic plants, algae-eating shrimps and a small number of fish. In this kind of fish tank, besides the common plankton, all the primary elements need to be complete. In fact, it is very easy to protect this aquatic ecological large aquarium, but it cannot be judged to be complete because of this. In this system, the share of each element is unbalanced. Because there are only a few fish inside, and there are few metabolic wastes, aquatic plants and bacteria are relatively excessive, and the water body presents a "negative nutrition" situation, which will lead to the overgrowth of aquatic plants in the fish tank, and the whole system will split. We need regular pruning to remove dead leaves and rotten leaves, and we should pay attention to adjusting the growth density of aquatic plants.
The protection of large aquarium is very important, so as to ensure the normal ecosystem of aquarium. It is necessary to adjust the variety and density of fish to make them reach a balanced state. However, this balance often changes. At this time, our protection work should also be adjusted accordingly. At the same time, we should pay attention to the cycle of changing water.
