It is said that there will be algae if the fish tank is not directly exposed to the sun, which will also affect the life of the fish tank. My fish tank wiped the window and was only caught in the corner by the sun. Is it okay? As long as the sunshine is not too strong, it is only good for ornamental fish, but the owner of the fish may be affected. The main factors involved are green moss, algae bloom and whether the water temperature is constant.

First, the formation of moss water can not be separated from sunlight, but it can not be excessive.

It is an eternal truth that everything depends on the sun. No matter goldfish, koi fish, ordinary tropical fish or advanced tropical fish, 99% of the fish can see sunlight under natural conditions, and proper illumination will be very beneficial to their growth and coat color.

At the same time, no matter what ornamental fish, moss water will not refuse. Moss can also be found everywhere in nature. The growth of moss in fish tanks also reflects the improvement of water quality.

Second, it is not a bad thing to raise fish in green water. Chlorella is harmless to fish.

In addition to moss water, excessive light can also produce Chlorella, which is free in water. Most omnivorous ornamental fish, especially larvae, feed on green water, so a small amount of green water has little to do with it and will only affect our ornamental effect.

One more thing, they will compete with Moss for territory, which we need to know.

Third, too much is not good.

But we must not think that the more mosses and Chlorella in the fish tank, the better, including mosses. If the number is too large, they will compete with the fish for oxygen at night, because our fish tank is not nature after all, and there will be many restrictions due to the size limit.

If there are too many mosses, they will die of aging or grow out of control. If there is too much Chlorella, the water quality will be turbid or even acidified, leading to the outbreak of pollinosis and tail burning in ornamental fish.

Therefore, we should manage everything moderately:

First, the fish tank should avoid light and try to avoid direct sunlight for too long.

We can make the fish tank grow a little moss, but there is also a problem, that is, the water temperature is too high in summer, so it is best to cover the back of the fish tank with thick background paper.

Usually, in order to watch, you must wipe off the moss on the front of the fish tank, which is also to prevent them from flooding.

Second, the fish tank should not be too small and the filtering equipment should be perfect.

The fish tank placed in a sunny place must not be too small, otherwise not only the water temperature is difficult to control, but also it is very likely that a tank of green water will be raised before the moss is generated, and it will eventually be uncontrollable.

Therefore, it is best to say that the aquarium facing the sun is about one meter, and the water temperature is relatively stable. Another is that the filtration equipment must be perfect, so that we can filter out the Chlorella produced in the aquarium in time, which is conducive to the growth of moss.

Third, there is plenty of sunshine in winter and proper shade in summer.

Doesn't mean sunshine is good, it depends. If it is 38 degrees every day in midsummer and the sun shines directly at noon, then the ornamental fish will not be grilled fish slices, will it?

Nothing is absolute. We should adjust the sunshine according to the climate and water temperature. If it is blocked, it will be blocked. It is time to change the water and strengthen the filtration. Only in this way can we raise ornamental fish.
