The reason why the grass tanks in the fish shops don't grow algae is that they are usually fed less, so that the water body will not be in a state of eutrophication, so it is not easy to grow algae. Of course, there are many reasons for the explosion of algae in fish tanks, such as too strong light, so as long as the appropriate shade, it is not easy to grow algae. In addition, adding algaecide to the tank regularly can also prevent the outbreak of algae.
1. Avoid direct sunlight: Algae prefer an environment with sufficient sunlight. If they are exposed to direct sunlight for a long time, they may explode. Therefore, it is necessary to avoid receiving direct sunlight for a long time at ordinary times. It is best not to put the fish tank in a sunny place. If you want to provide light, you can prepare some special aquarium lights.
2. Change the water regularly: By changing the water regularly, the water quality can be kept clear, so that the possibility of algae explosion will be greatly reduced. Usually a week to change the water, change the water to change about a quarter, if too much, it will stimulate the fish, let it produce some stress response, harmful to health.
3. Reduce feeding: When feeding fish at ordinary times, be sure to pay attention to food intake. If you feed too much, you will produce a lot of residual bait, and excrement will increase, which will enrich the water and provide a growing environment for algae. As long as the amount of feeding is reduced, algae will not be easy to reproduce.
