Fish first water, water first bacteria! This cliché topic fish friends are tired of hearing, the reason everyone understands, but how to raise water?
Aquaculture, as the name suggests, is to help the water body to establish an ecological environment that can "simulate nature" and create a comfortable and healthy ecological balance for aquatic animals. So that the water body in a certain period of time (such as 1 week - 1 month) can reach a benign internal circulation, and through the decomposition of beneficial biochemical bacteria to decompose the water harmful to the fish of ammonia nitrogen, nitrites and other harmful substances, so as to maintain long-term stability and excellent water quality.
The establishment of nitrifying bacteria is to help the process of water nourishment. To put it bluntly, the essence of water conservation is to "cultivate bacteria", what kind of bacteria?
No doubt about it, nitrifying bacteria!
As we all know, koi do not have a stomach, feed more eat more, pull more, and fish feces is the main source of water toxicity - "ammonia, nitrogen", at the moment there is no fish friend suddenly realized that your fish is likely to be fish feces "! The fish feces is the main source of ammonia and nitrogen, which are highly toxic in the water.
And the cultivation and propagation of nitrifying bacteria is the role of biochemical filtration. The biochemical filtration system cultivates nitrifying bacteria used to decompose and transform ammonia nitrogen, nitrite and other toxic substances in the fish pond, so that the microbial flora in the fish pond reaches a balance, thus establishing a complete set of ecosystem.
The role of the filter media is to provide the nitrifying bacteria with a place to bed, that is, long-term survival of the "home". That said, nitrifying bacteria are naturally delicate, sensitive to the living environment and demanding, can not be neglected! Otherwise, it will turn its face faster than a book!
Then we find a clear answer to the question of how to choose filter media - look for high quality filter media that is conducive to hosting more beneficial bacteria.
Fish first water, water is to get filtration, the key to get filtration in the biochemical filtration media multiplied by the number and quality plus reasonable water circulation.
Filter Material Classification:
There are two types of filtration media, a physical media that blocks impurities or dirt visible to the naked eye, and a biochemical media whose mission is to host more nitrifying bacteria.
Physical filters: filter cotton, brushes, rattan cotton and the like, stockings can be considered physical filters.
Biochemical filter media: common biochemical felt, biochemical ring, biochemical ball, infrared bacteria house and so on, although there are more categories, but their role is only one, is to host bacteria.
Brushes are relatively effective physical filter media. Both traditional filtration tanks and smart integrated fish pond filters have a separate compartment or two where brushes are placed as primary coarse filtration, which can be washed and reused.
Filter cotton is often placed in the top of each bin, this is considered a low-cost, and blocking the role of good physical filter material. Note that the filter cotton block can not appear around the overflow phenomenon, otherwise the loss of impurity particles, aggravating the burden of biochemical filtration.
Physical filtration media will be briefly mentioned, and below we will talk about biochemical filtration media.
Filter media is used for biochemical filtration, so it's best not to affect the water quality priority, then we'd better use neutral filter media. Neutral filter media is the filter media that will not have an additional impact on the PH/GH indicators of the water, then coral stone this kind of filter media to raise PH, ceramic ring to raise GH should be cautious, if it is a grass tank then these two should be passed over.
That leaves us to start thinking about which one to pick in terms of what it's actually here to do.
Nitrification system to establish in fact is to cultivate nitrifying bacteria will be in the water of ammonia and nitrogen decomposition to restore water quality, this truth is known to everyone, but nitrifying bacteria only one kind of bacteria?
NO, in fact, there are more than N kinds, we roughly classified into two kinds, aerobic bacteria and anaerobic bacteria, these two kinds of bacteria preferred habitat of the filter media is different, so we will look at the filter media as their house, to buy their favorite house, in order to attract them to adhere to thus establish a good nitrification system.
First buy aerobic bacteria house, aerobic bacteria generally like in the holes, good water flow circulation of the filter material, so bacteria house, bacteria ring, bacteria brick, ceramic ring such as the appearance of rough are small holes in the filter material is the first choice of aerobic bacteria mansion. But usually one or two choices of filter media for the same function is enough, because the function is the same, and you don't need too many kinds.
The second is anaerobic bacteria, anaerobic bacteria like to inhabit in the nanosphere, hollow ball of these outside solid inside hollow filter media, so the natural choice of these two kinds of filter media on it.
So in summary belongs to the general set of biochemical filter media, no more than 3 kinds, of course, many filter media now also add a lot of ancillary functions such as deodorization, stabilization of PH and so on the claim that there is also some effect, but the price is slightly more expensive, if you do not pursue these, completely direct choice of the filter media used on the line.
