Well, not exactly chlorine. Tap water is pressurized and therefore has more gases dissolved in it than water under normal conditions. High partial pressure of oxygen gas and carbon dioxide forces the fish to adapt to the new conditions. Which they do successfully. But after 20 minutes, the concentration of gas in the water begins to fall sharply on the walls of the bubbles and partial pressure changes again, but in another direction. And it turns out a very dangerous situation for fish partial pressure of oxygen inside the fish becomes more than in the environment, and as a result oxygen starvation develops. CO2 leaves the blood, and as a consequence, asphyxia and death. So the question is not about chlorine, but physics and physiology A water is enough to stand 2 days for 50 liters and it is quite suitable for settlement. So there you go. If you need more detailed explanations, welcome to the mail or agent.

to get the chlorine out.

For at least a DAY with the lid open. To get the chlorine out.

To let the chlorine escape and sediment from the water pipes

that all the crap that's in it settles to the bottom so your fish don't die.

This is a misconception. Fish grow better and feel better in fresh water. Changing the water every 3 days 1/3 of the total volume is recommended. For fry, half a volume every day!

let the chlorine evaporate and the impurities precipitate.

A week - And the hell with the chlorine! Tap water is oversaturated with oxygen and it destroys the edge of the fins and skin of fish. The damaged tissue then rots. Again, the same microflora is formed. But if you change less than a third, you can not defend.

We have such water that it unless the mutants can stand, but they need a settled from the chlorine and other particles!

Usually tap water contains a number of undesirable components: 1. Disinfectant. In the former Soviet Union it is usually chlorine, and sometimes fluorine or ozone are used. All three gases are very poisonous 2. The water is fed under pressure and supersaturated with dissolved air. If you put the fish in such water in the internal organs can be formed bubbles, and it is fraught. Dissolved air is probably the most significant adverse factor 3. The water may contain unwanted suspended solids. Iron hydroxide in particular sludge rusty In addition plumbing water in winter has a temperature of 2 degrees and fish can catch cold Otsastivanie water is not the only way in which it can be prepared for the aquarium. But it is simple and requires no effort. Therefore, it is the most popular in the former Soviet Union. But in Florida, for example, like to put the water in the bright sun in a shallow trough.

We have good artesian water. Nothing I do not defend the first time of course engaged in it, but no bubbles were not and just filled the aquarium full and all is well. now I always do so without defending
