If you want to protect a large fish tank, the most important thing you need to do is to clarify the key elements it lacks, and see if the share between the elements it places is appropriate. If it has fewer elements, the closer the share of each element is to natural conditions, the less protection work will be required. Otherwise, the more protection work will be required.
Set up a "naked tank" for pure fish farming with only submerged biochemical filters. This kind of tank should achieve the effect of looking full for appreciation. Under normal circumstances, the density of the fish fed will often reach the filter of the fish tank. In this case, the share of bacteria and fish will be out of balance.
If this kind of fish tank is to be protected, in addition to feeding the fish every day, it is also necessary to regularly suck out the residual bait and feces at the bottom of the fish tank, and to change the water frequently, so as to better dilute the harmful waste in the fish tank. When the water temperature is high, you need to use an air pump to invigorate. This depends on the species of fish to make specific decisions.
Set up a "waterweed large appreciation fish tank" with biochemical filters, bottom sand, a lot of water plants, algae-eating shrimp and a few fish. In this type of fish tank, except for the common plankton, all the main elements are required. In practice, this kind of large-scale aquatic ecological appreciation fish tank is very easy to protect, but it cannot be judged to be complete because of this. In this system, the share of each element is unbalanced.
Because there are very few fish in it, and very few metabolic wastes, aquatic plants and bacteria are relatively excessive, and the water body has "negative differentiation". This will cause the aquatic plants in the fish tank to grow wildly and the entire system will collapse. We need to trim regularly, remove dead leaves and rotten leaves, and pay attention to adjusting the growth density of water plants.
The protection of large fish tanks is very important, so as to ensure the normal ecosystem of the fish tanks. It is necessary to adjust the species and density of fish so that they can reach a balanced state. However, this balance often changes. At this time, our protection operations must be adjusted accordingly, and we must pay attention to its water change cycle.
