Hello fellow aquarists! If you have any questions about raising ornamental fish , you can directly search for fish farming experts and keywords on the entire Internet, so that we can easily raise water and happily raise fish.

Sometimes some aquarists ask questions that I find really difficult to answer.

For example, an aquarist today, after keeping fish for less than half a month, several small tropical fish died, so he impatiently dumped the tank, changed all the water, and then started cleaning the filter material, without asking whether it was necessary. Cleaning, but asking how should it be cleaned? Does

use tap water? Does it have to use original tank water? What should I do after washing? Do I need to disinfect again?

This question troubles me. How should I answer it?

My principle is that even if the ornamental fish has a serious illness and dies, I will not clean the filter material

I don’t care what others do, how mysterious the problem of the dead fish is, or how careful the operation is.

Anyway, in my place, even the whole tank of fish said goodbye. No matter what the reason is, I am too lazy to clean or replace the biochemical filter material.

At most, it is possible to leave it alone for a few days without raising fish. It is possible to do a large water change in the entire tank or to empty the tank for half a month.

Or if you are happy one day, fill the whole tank with potassium permanganate and bubbles, including the filter material, or bubble with salt water.

I have been raising fish for so many years and have been doing self-media for five years. I have videos and articles. When will you see me cleaning the filter material? In addition to simple cleaning of newly purchased .

Cleaning is possible only when all kinds of impurities have been dealt with and the filter material has been used for a long time.

No matter what problems occur with the water quality of the fish tank, pumping the bottom, changing the water, wiping the tank wall, and cleaning the filter cotton are all basic operations. Routines include fishing out dead fish or isolating sick fish.

After everything has been taken care of, including the sedimentation chamber, water pump chamber, etc., one by one, if the water quality is still bad and the condition of the ornamental fish is still not good, and we can basically judge that it is caused by water quality problems.

Such as: timidity, lying on the cylinder, shrinking fins, red blood streaks, etc...

Moreover, the service life of filter material is at least one or two years. At this time, consider cleaning the filter material. Why do some

cleaning times take a short time while others take a long time?

So, why do some aquarists clean or replace the filter material immediately after using it for a year, and some still have no problem after three to five years?

will have the following reasons:

1, stocking density and physical filtration

The stocking density is high, the feeding amount is large, and the physical filtration always overflows, resulting in the accumulation of impurities in the biochemical filter material. In this case, the filter The toxins in the material warehouse may exceed the standard, and the aging time of the filter material will be accelerated.

2. Placement problems and quality problems

The filter material is placed unreasonably or too densely, the water flow is not smooth, the quality of the filter material is poor, it pulverizes frequently or keeps falling off. When

encounters these situations, of course we need to clean it up in time or replace it appropriately.

3. Fish keep dying and getting sick, and the filtration is not good.

Fish keep dying in the fish tank, ornamental fish keep getting sick, and the physical filtration is not good, resulting in all kinds of soup and water constantly entering the bottom filter bin , and the overall water quality is long-term turbid. Like rice soup, then this filter material cannot be any better.

At this time, if this continues for a long time, the filter material in the tank may be scrapped soon.

4. Careful, very careful fish farming

There are also some aquarists who are very careful and seek peace of mind at all times. They are afraid that the endotoxin of the filter material will exceed the standard, and they are afraid that the filter material will pulverize at any time.

No matter if it is less than the expiration date, it will be discarded after one year of use. There are many aquarists like this. This is another problem.

Of course, there are also some aquarists who will completely turn over the tank as soon as the fish becomes sick, one or two dead fish appear, or there are protein worms and the like. That is another matter.

So, don’t look at how often others clean their filter materials, but look at your own actual situation. Blindly learning from others may not be a good thing. The last point of

, how to wash it?

Since it needs to be cleaned or replaced, do you still care about the bacteria on it?

can be washed as cleanly as possible. can be washed with any water, as long as it is clean.

Whether you use bath towel, steel wool, or grinding stone, high-pressure water gun, you can use whatever method feels comfortable to you, but try not to use chemical reagents, such as laundry detergent, Shower gel , 84 disinfectant , dichlorvos ... forget about these.

In most cases, there is no need to disinfect it after cleaning. If you are not worried, can be exposed to the sun for a few days, or can be steamed.

So I don’t understand why novice aquarists focus not on the frequency of cleaning, but on the cleaning method?

Who is it that has led all our aquarists astray?

I am an experienced fish farmer. Please stay tuned for more ornamental fish issues. Thank you!
