Correctly equipped and properly the served aquarium in which biological balance is maintained can not demand changes of water throughout long time. The water turbidity problem most often arises at the beginning aquarians considering that care of small fishes consists only in plentiful and timely feeding.
Instruction
1. Water becomes muddy because of the small particles of soil which appeared in it washed away during careless filling of an aquarium by water. After they settle on a bottom, water will become clear again. You do not make full replacement of water when it is not required. By means of a rubber or glass tube periodically remove the dirt accumulating at the bottom and add necessary amount of fresh water, watching that its temperature coincided with the water which is in an aquarium.
2. Water can dim also in the new, just equipped aquarium, owing to reproduction of unicells. This phenomenon carries the name "infusorial dregs". You do not hurry to occupy the aquarium prepared and filled in with water, wait several days. Other harmless reason of turbidity – a soil vzrykhleniye the fishes rummaging in it – easily is eliminated by the placement on a bottom of a layer of carefully washed out sand.
3. Turbidity of water can be caused by emergence of a large number very harmful to fishes and plants of putrefactive bacteria because of too high concentration of fishes in an aquarium or the wrong feeding. Observe one of the basic rules of aquarium husbandry: "It is better to underfeed, than to overfeed".
4. If you forget to remove the remains of a forage and the decaying plants in time, it can also provoke rough reproduction of bacteria. Besides, turbidity can be caused by bad filtration and blowing off of water as a result of which in an aquarium there is an accumulation of the products of exchange serving as the ideal environment for mass reproduction and food of bacteria. To avoid similar consequences, transplant excess fishes and improve the system of filtration.
