The green algae in the tank wall does not mean that the water quality is poor, but that the water quality is rich. This kind of water is still harmful to fish, because the organic matter content in the water is too high. When they are decomposed by microorganisms, they will produce ammonia nitrogen, which is a substance that harms the health of fish.

However, after the occurrence of water bloom, algae can absorb some ammonia nitrogen, thus improving the water body to a certain extent, but it will also increase oxygen consumption. Therefore, it is necessary to prevent algae from erupting at ordinary times and clean them up in time after they grow.

Tip:

When changing water, the algae on the pond wall are scraped off by scraper, swipe card or technological foam, and sucked out along the water pipe, so that the whole algae group is removed in large quantities, and the fresh water dilutes the factors causing algae outbreak.

Otherwise, just like scraping the cylinder wall, the algae will disperse instead of decreasing, and the effect is of course much worse. As long as the above scraping method is continued for about three or four times, and at least a large number of 1/2 water is replaced, the condition of the whole water tank will be greatly improved. However, this is only a temporary solution, and it is the only way to eliminate algae permanently and continuously.
