The round fish pond is a favorite for fish farming enthusiasts, which is both beautiful and practical. However, the problem of algae breeding often troubles fish pond owners. Excessive algae proliferation will not only affect the aesthetics of fish ponds, but may also lead to deterioration of water quality and pose a threat to the living environment of fish. Here are some effective ways to prevent the growth of algae in round fish ponds.

First of all, controlling lighting is a key part. The growth of algae is inseparable from sunlight, so reasonable adjustment of the light time and intensity in the fish pond can effectively inhibit its growth. If the fish pond is in a position where direct sunlight lasts for a long time, consider building a sunshade net to reduce the duration of direct sunlight exposure, especially in summer when algae blooms vigorously. Generally speaking, ensuring 4 - 6 hours of soft light per day can meet the needs of fish while inhibiting algae growth.

Secondly, optimizing the filtration system is crucial. The powerful and efficient filtration system can remove nutrients from the water in a timely manner, which are the "hotbeds" for algae breeding. Choose a comprehensive filtration equipment that includes physical, biological and chemical filtration. Physical filtration can intercept impurities and algae spores in the water, biological filtration can decompose organic matter in the water through beneficial microorganisms, and chemical filtration can adsorb some substances that cause algae growth. Clean and replace filter materials regularly to ensure that the filter system is always in good working condition.

Moreover, reasonable control of fish numbers and feeding amounts cannot be ignored. Too much fish will produce a large amount of waste, and excessive feeding will cause food residue to accumulate in the water, which will increase the nutrients in the water and promote algae growth. According to the size of the fish pond and the capacity of the filtration system, the stocking density of fish is scientifically determined, and the principle of eating less and more meals is followed to avoid feed residues.

In addition, regular water changes are also an effective means to prevent the growth of algae. Changing water by 10% - 20% every week can dilute nutrients in the water and reduce the possibility of algae breeding. When changing water, pay attention to the quality of new water, carry out dechlorination treatment in advance, and ensure that the water temperature, pH and other parameters of the new water are similar to those of the original water to avoid causing stress reactions to fish.

Finally, you can consider putting some algae-eating organisms in fish ponds, such as scavenger fish, black-shell shrimp, etc. They can help clean up algae, but attention should be paid to the selection of biological species and quantity control to prevent the introduction of new ecological problems.

Through the implementation of the above comprehensive measures, we can effectively prevent the growth of algae in the round fish pond, keep the water quality of the fish pond clear, create a healthy and comfortable living environment for the fish, and make your fish farming life more comfortable.
