I. Reasons
The water in the fish tank turns green, mainly because the green algae in the water grow too vigorously. The main reasons for this situation are: long nursing time in the fish tank; The proportion of aquatic plants is too lush, which leads to the failure of the filter to discharge pollutants normally and the water quality is polluted; Fish feed is overfeeded and decays in water, which becomes the nutrient of green algae.
Second, the solution
1, if it is because of the process of fish tank lighting time that the green algae grow wantonly, just take measures to avoid light and reduce fish tank lighting time, which can slow down the growth of green algae and effectively solve the problem of water turning green.
2. If the amount of green algae in the fish tank is far greater than the total amount of fish, even the filter can't work normally, then only the filter system of the fish tank needs to be improved to alleviate the situation that the water turns green, or some green algae can be removed, which can also achieve the mitigation effect.
What effect does the fish tank water turn green have on the fish?
1, the water in the fish tank turns green, which means its visibility and transparency are also reduced. This is our first feeling when we see the green water, but the ornamental fish is different. Especially some wild ornamental fish, their visibility in green water has also decreased. So it is equivalent to giving them a layer of natural protective color and increasing their sense of security.
2. Green water contains a lot of microorganisms, so it can also provide some newborn fish with better open food. Especially the viviparous giant fish like peacock fish, Mickey fish and Mary fish, their small fish can eat feed directly, and the abundant microorganisms in the green water just give them natural feed.
