Water change in the aquarium

Many novice heard this expression. We will understand what it is and whether it is at all.

The aquarium is a fully closed system in which everything must be in equilibrium. But, often beginners, this equilibrium does not exist in principle, which could contribute to any beginner steps: from the start of the three dozen fish in 15 gallon tank until vpihivaniya couple pounds of aquarium chemistry.

Then our beginner rushes frantically to carry out a water change. Yeah, know read.

Water change in the aquarium nothing is going to have. Fish swim belly up, the plants continue to rot. Repin’s Painting: “Came”.

Why the need for a water change in the aquarium

Let’s first define what you mean by spoofing, since many beginners confused with the water changes.

Substitution of water is, roughly speaking, the infusion of 1/3-1/5 of the volume of water in the aquarium.

Reasons for the necessity of this infusion can be many:

A small amount of oxygen in the water

This is manifested in the fact that all fish swim under the surface and swallow air. If time won’t find out, they smoothly roll over belly-up, that is to say die. This happens with a small number of plants in the aquarium and broken Aquarian compressor. here you’ll have to substitute water, but still stick to mix the layers vodev the aquarium.

High concentration of nitrites/nitrates

It leads to the prohibitive concentrations of nitrites or ammonia. To reduce the concentration quickly and easily, you can only water in the aquarium. But, in any case, do not change the water completely or so.

Paradoxically, but the water in the aquarium tends to age. The balance of the aquarium are perfectly normal, the nitrates within reasonable that you have checked the appropriate test. But, the behavior of the fish you a little confused. Do not play, do not breed. Makes sense, at least for validation, to produce a partial water change .

I have, in the old vintage tanks, a water change is a resounding success. Fish cheerful start to run, the plants become very quickly a more bright and juicy.

Turbidity of water

As a General rule. turbidity in normal working aquarium, means one thing. Something dragged. And most likely, occurred the so-called bacteriological flash. To solve your problem, in this case, a water change will not help. But, it will reduce the concentration of these bacteria that will facilitate restoration of bio balance in the tank.

Water changes in the aquarium

Not highly recommended procedure. Since you will have to re-start the aquarium, in fact. Apply it carefully and deliberately.

To make the replacement water necessary in the case of the aquarium, which categorically does not want to run in the normal bio-cycle.

As a rule, if to make an analysis of water from this aquarium, there is an increased content of any chemical compounds. So take responsibly to the procedure of preparation of water to run, the ground, caves. the driftwood, rocks and other decorations .
