The best remedy for poor water quality in a fish tank is to install a filter. Filtration has two functions to maintain water quality, one is to prevent it from becoming stagnant water by forming water flow, which will slow down the deterioration of water body. The other is to use filter material to clean up the dirt in the water, so that the water becomes clear.
bare tank fish, the water quality is easy to deteriorate, but if you add some sand in the tank is not the same. Bottom sand can not only play a filtering effect, but also provide a place for beneficial bacteria to grow and reproduce, with which they can decompose organic matter that deteriorates water quality, and at the same time convert it into nitrate that is harmless to fish.
Fish farming must change water, through which water quality can also be improved. Usually once a week, if the water quality is good, it can also be changed once half a month. Do not change too much water each time, although more water to improve the water body, but also stimulate the fish, each time for a quarter of it.
It is best not to put the fish tank in a place with strong light, because this will increase the risk of algae explosion, once the algae explosion, the water quality will deteriorate. Therefore, it is better to put it in a bright place, or use special lamps to illuminate the fish tank, so that algae will not erupt.
