the position of the anti-siphon hole of the fish tank? The position of the anti-siphon hole of the fish tank is related to the water level of the main tank. Generally, the hole is drilled 1.5 cm below the water level, so as to ensure that when the water level drops, the siphon will stop when the air enters the hole, so as to prevent water from running. The anti-siphon hole is usually only needed in the bottom filter fish tank, which is divided into two parts, the main tank and the bottom tank, and the water flow will continuously pass through the two tanks, so that the water quality can be maintained.
is needed for the fish tank? 1. Filter: The filter is an essential equipment in the fish tank. Its function is to maintain the water quality. The big fish tank generally uses the bottom filter, while the small fish tank can use the upper filter or the filter cartridge. The filter can not only filter out the impurities in the water, but also cultivate the nitrifying bacteria, so as to convert the ammonia nitrogen in the water. Avoid poisoning the fish.
2, oxygen pump: If the fish is very large, or the number is relatively large, the oxygen in the water is often not enough, which requires the preparation of oxygen pumps. Oxygen pumps are usually turned on 24 hours a day to prevent fish from suffering from hypoxia. If there are not many fish, the oxygen pump can also be used in stages.
3. Aquarium lamp: Generally, the fish tank can not be placed in the sun, otherwise it will lead to excessive temperature difference, and it is easy to explode algae. Therefore, aquarium lamps need to be prepared in the tank to provide 6-8 hours of light every day, so as to meet the needs of fish.
