Nitrifying bacteria vs big salt, does salt kill nitrifying bacteria

You just need to put the nitrifying bacteria in the tank when you open it, but make sure you have a ceramic ring inside the filter tank. In that case, you don't need to add nitrifying bacteria every time you change the water, and that's just the fish shop owner fooling you.

Salt, it should be big salt is not edible salt at home, edible salt can stabilize the water quality, if the water is good, you don't need to put it, the Arowana fight off the scales can add a little more salt Remember that it is not edible salt.

And salt can't be put casually, if you put salt often, it won't work when the fish is sick and you want to put salt.

It's like people take medicine when they are not sick, and if you take too much medicine, you won't see the effective results when you are sick.

First of all, I want to know why I put these 2 things every time I change the water.

In addition to the use of nitrifying bacteria when opening the cylinder.

Wait for the fish, under normal circumstances, this thing is not put in, because it usually takes more than half a month to wait until the tank is opened to the fish, because at this time the nitrifying bacteria system has been basically established.

As for the big salt. I would like to ask if it is the coarse salt that you usually eat? If so, I can't understand even more, why put it.

If you believe me, then don't put these 2 things.

As long as the filtration is strong enough, it can be exchanged for 1/4 of the water a week.

None of this is needed.

But if I'm wrong, then please tell me what the purpose of putting this thing is, and what is the basis. So that I can learn and learn. Thank you.

No. Nitrifying bacteria have a considerable tolerance for changes in salinity osmolality.

Scientists have used the properties of osmotic pressure of the solution to measure the dehydration effect of bacteria in water, showing that bacteria cannot live in water with too high dissolved substances, and if the salt content in the water is very high, it will cause sensitive bacteria to dehydrate and die; Conversely, water that is too pure is not suitable for bacteria, because the substances dissolved in the cytoplasm will absorb water and overswell and die. As a result, many bacteria have varying adaptations to osmotic pressure of salinity, with some surviving only in seawater and others in freshwater.

Therefore, nitrifying bacteria can live in both seawater and freshwater.

The purpose of salt in the fish tank is to sterilize and release fish diseases, so most of the ornamental fish are usually salted, which is the basic common sense of raising fish, so does salt have any effect on nitrifying bacteria? The answer is yes! One thing that can be done for sure, and that is to domesticate nitrifying bacteria!

Nitrifying bacteria are abundant in the silt of ditches and ponds, and are two types of microorganisms: bacteria and yeast. If you want to cultivate quickly, you can buy it in the market, and plastic bottles are not expensive. In practical application, the main thing is to deal with the filter cotton, the filter cotton can not be washed often, as long as the filter cotton can still permeate the water, do not wash, see the filter cotton is very black, it is a good environment for the growth of nitrifying bacteria, when the filter cotton is not permeable, rinse the solid matter above with clean water, you can't use soap, and don't make the filter cotton too clean.

Summary. 1. Salt can play a role in sterilization, but there are certain requirements for concentration, usually the concentration of salt in the fish tank does not exceed five thousandths, this concentration can not be sterilized, the purpose of salt is not to sterilize, but to improve the osmotic pressure of water to prevent the invasion of bacteria. If you change the water frequently and stop filtration, the damage of nitrifying bacteria will increase, so you need to be careful.

If you change the water frequently and stop filtration, the damage of nitrifying bacteria will increase, so you need to be careful.

2. The types of ornamental fish include freshwater fish and marine fish, but the salt environment of marine fish is 30-40ppt (that is, 30-40), so it is obvious that it will not affect the nitrifying bacteria. As long as your fish is alive, then the nitrifying bacteria are alive as well. Unless the water becomes pure salt water, then the fish die, and the bacteria are almost dead.

Freshwater fish tanks are salted, and the hand only treats the fish, and the salinity does not exceed 10ppt
