Hello everyone! If you have any ornamental fish feeding problems, you can directly search for fish raising old ways and keywords on the entire network, such as fish raising old ways, water quality white and turbid, fish raising old ways, ornamental fish black spots, rot disease , etc.
There has always been controversy in the fish farming circle about changing water to ornamental fish, because the frequency of water change between aquarius friends is too different.
Some aquarius may have to change the water every week or three or five days, but what about it? Change it every half month or twenty days, and there are even longer ones, and it may only be replaced every few months or even one or two years, especially outdoor fish ponds. We can often see such videos on the Internet.
So, are these practices right or wrong? Why can people’s fish tanks still make the water clear and bright without changing the water for such a long time?
The number of fish and how many are fed differently
low density and small amounts of feeding can reduce the frequency of water change or the amount of water change. , especially for raising some more solid ornamental fish, is the case with water index that is more tolerant or small ornamental fish.
We say that changing water is the main function not only to remove organic matter and impurities in the fish tank, but more importantly, it also needs to inject fresh blood and various trace elements into the fish tank.
has extremely low density, very little feeding, or there are a lot of natural bait in the outdoor environment, which is easier to digest. In addition, there will be some denitrification at the bottom of the tank or pool. forms a good ecological cycle, which is very likely to extend the water change cycle.
is a relatively powerful filter system or plant system
. It also has a very powerful filter system, which can discharge sewage systems or assist plants at any time. The plants themselves can absorb a lot of toxic substances in the fish tank, and better assist the filter system. In addition, has a wide water body and low density and other reasons, the water quality may be well maintained.
Another key is that the tolerance of ornamental fish is also different.
However, planting plants in the fish tank is not a good thing, and it will still affect the activity space and breathing of ornamental fish, and it also needs to be pruned in time. As the saying goes, things will turn back when extremes, and it cannot be done once and for all.
There is always some work that we need to do.
There are still many small movements, but there is no major change of water
If the filtration system in the fish tank is not very powerful and does not have the assistance of the plant system, then there may be some small movements.
For example, regularly pump the bottom and remove impurities in the bottom and wall of the cylinder, regularly clean the filter cotton , replace the filter cotton, if there is strong discharge, you can discharge sewage regularly. Due to evaporation and lack of water, add a small amount of fresh water regularly, and replenish water for the fish tank or bottom and filter from time to time. The weather is stuffy and the feeding amount is reduced.
Outdoor fish pond, on rainy days, God helps to rehydrate automatically, or there is a 24-hour drip system. These situations are possible, including the appearance of dead fish in the middle, which invisibly reduces the feeding density.
These many small operations are equivalent to changing water to the fish tank again. It is just the quantity and frequency of replacement, and there is no longer so-called regular water change.
If it is a naked tank less than one meter and two, it is unlikely that it will not change the water for a few months
If it is only a naked tank with a fish of one meter and two or less, the density is moderate and feeding it every day, if it wants to ensure the water is clear and the fish is bright, it is unlikely that it will not change the water for a few months.
Because even if it continues to evaporate, it has not much water after a few months.
Either the original cylinder must be filled with water, or the water pump of the bottom filter system may have been idle for a long time.
The so-called clear water and bright fish. If you don’t change the water for several months, there must be other conditions. Otherwise, if you raise fish in a small tank, the rough water change cycle will be only two months at most. It may be a little longer in winter. What about summer? It is impossible to have more than two months, and it is impossible to have water dripping in the fish tank.
Many old aquarius friends have proposed that the water change cycle can be appropriately extended, but it is just to avoid novice aquarius friends from over-trotting.
After all, when you first started raising fish, the main concern is that the water quality is stable. Only by completely stabilizing the water quality can you ensure clear water and bright fish.
Then we decide our own fish tank water change cycle according to our feeding density and feeding volume, and it is impossible for us to never change the water.
I am a fish-raising master. Please pay attention to more ornamental fish questions, thank you!
