Fish tank water quality problem!How to judge the water quality of the new fish tank?

According to the analysis of the younger brother, the reason why your water is not transparent enough, is because the water has a large number of tiny impurities, these impurities are small enough to pass through the filtration system, I used to go to the fish shop to see the boss is adding something to the water, it should be the use of electric charge, the original because the very small impurities with the same charge and the formation of the impurities in the colloidal suspension with different charges and attract each other together, into a larger impurity group, so that after entering the filtration system can be successfully filtered out.

What the hell is this thing?Maybe it's alum, I've seen cases where you put alum in the water and the water quickly becomes clear and transparent, but there are also cases where the aluminum in the alum increases the chance of people drinking this water to get Alzheimer's, and I don't know if fish can get Alzheimer's disease, so I declare that I am not legally responsible for the Alzheimer's disease of fish in a few years as you and I suggested.

The owner of the fish shop raises fish for sale, not for raising, so his breeding is only the most basic requirement to ensure that the fish does not die, do not get sick, and do not change color. He has the same purpose as you raise fish, you have to raise fish. Therefore, he feeds very little, and you have to feed hard.

As a result, your water will never be as clear as theirs. Unless you feed less, you can only ensure that the fish do not die.

Again, you buy a finished cylinder, the filtration system is moderately powerful, they do it themselves, and they are equipped with high-power filter pumps, unless you also add it, but it affects the appearance.

At the same time, in addition to selling fish, he is cleaning up, which is his daily work, and you are a hobby, you can't spend so much time doing cleaning work.

So, you still don't want to be too high, as long as there is no problem with the water quality.

It is certain that the fish shop feeds less, and the most important thing is that his filtration system and the cultivation of digestive bacteria cannot be achieved by family fish farming (he has a place), and as for changing the water, no one will change it every day. Your filtration system should be fine, it's nitrifying bacteria that aren't cultured well. You buy some nitrifying bacteria to put (note that nitrifying bacteria are fake, really colorless, tasteless and impurities, and the shelf life is half a year).

When washing the filter cotton again, use the original tank water (tap water will kill nitrifying bacteria). I basically don't need to change the water, just add a little water to the water level for more than 2 days after 3-4 days.

It's not like you have a bucket.

Instead, it needs to have the right flow and use it correctly. The process of water cultivation is complete, and nitrification can be cultivated.

It's not that you have a bucket and pour in some bottles of so-called nitrated rotten egg water.

If nitrification is not strong enough, any problems will occur in the future, don't worry.

In addition to the strong filtration system, the fish shop also has to change the water every day. As for the little feeding that is said upstairs, this should be for those small aquariums, generally large ones will have technicians who specialize in feeding fish, feeding no less than three times a day, in addition to filtration, the main problem is to change the water.

Aquarium knowledge, how to judge the quality of the fish tank, look at these 3 aspects.

The three indicators of fish tank water quality are pH, ammonia nitrogen, and nitrite.

1. pH: pH is a very important indicator to measure the water quality of a fish tank, which is often called pH value. Generally speaking, the pH ranges from 1 to 14 and is mediated by 7.

A pH from 1 7 indicates that the water is acidic, and a pH from 7 14 indicates that the water is alkaline. pH=7 water is neutral. Therefore, the closer the pH value is to 7, the less alkaline or acidic the water is.

2. Ammonia nitrogen: the content of ammonia nitrogen in the water body, two indicators, one is the content of ammonia, and the other is the content of nitrogen. Ammonia is poisonous, both to humans and to fish, but nitrogen is not toxic, and it usually quickly becomes nitrogen and volatilizes into water.

Therefore, it is generally more concerned about the content of ammonia in water, and it is more commonly used to test the content of ammonia in water. Generally, the content of ammonia nitrogen can be controlled as follows.

3. Nitrite: Nitrite is also used in the fish tank water to convert ammonia into nitrite with less toxicity through nitrifying bacteria. Although nitrite toxicity is relatively small, it still has a relatively large impact on ornamental fish.

Therefore, it is necessary to control the low nitrite content in the water. Measuring the nitrite content in the fish tank water is also using the nitrite test solution, which is almost the same as measuring ammonia nitrogen, which is to use some liquid chemical reactions, and then let these test solutions change color, and then we compare the color on the display card to know the nitrite content. Generally, the nitrate content of water is less than milligrams per liter.
