It is possible to turn off the water pump for the night only if you have it "for beauty". Usually, the air pump is installed if the fish do not have enough oxygen dissolved in the water (this does not include labyrinth fish and have intestinal breathing – they do not care how much oxygen is in the water – they breathe atmospheric air) or to secure the filter in case the latter fails ( This will not be a problem if in the aquarium there are instead of one filter – two are weaker or there is a filter and a pump).
If you have a filter in an aquarium, it usually has the function of supplying air bubbles to the water column, but water saturation with oxygen occurs not only due to bubbles, but also due to mixing of water and constant updating of its near-surface layer, which completely provides an internal filter. or pump. Live plants also provide fish with oxygen, but only during the day, producing it in the process of photosynthesis. But plants also breathe, and at night they absorb oxygen, and they emit carbon dioxide. An excess of plants can create an oxygen deficiency at night, so the water pump is right at night and relevant when the plants absorb oxygen and release CO2. If there are a lot of plants and a decent amount of fish – starvation is quite possible. During the day, the water pump is useful only in the case of overpopulation or in the absence of plants. So, it all depends on the number of plants and the number of fish.
If you do not know if you need a water pump at night, you can experiment by turning off the water pump for one night. It is only advisable to stand up sometimes and check the condition of the fish – if they swim at the surface by swallowing air, it means they do not have enough oxygen and have to leave the air pump or reduce the number of plants. Accordingly, if the fish swim in the water column until the morning, then a water pump is not needed at all.
But do not forget that the water pump performs another important function – mixing water. Without this, the water may stagnate with the formation of an unattractive film on the surface, the water temperature may be different in different layers, some fish like the flow. Again, if there is a filter or pump, then they will also mix the water.
And yet – whether we like it or not – the fish are growing. And if there is enough oxygen in your aquarium that does not change its size today, it’s not a fact that it will be enough tomorrow. Therefore, safety net never hurts.
If a water pump bothers you at night, try moving it to a non-residential area, and lay only an air hose from it (the length does not play a special role). You can hide the water pump in a foam box with space to avoid overheating of the water pump. Well, or buy a quieter model, of course, it will cost more, but you take it not for one day. Also, as an option, the purchase of an aerator operating on the pump principle – they are practically silent (like filters), come with color illumination (very nice, especially at night), the only negative – cost, unlike a noisy Chinese, is expensive (although, of course, relatively).
If the water pump is broken.
If the water pump is buzzing but the air does not enter the aquarium, it usually means that the air duct has been disconnected from the pump at some point or the membrane of the vibrator pump has been torn. For this case, be sure to keep another membrane in stock and replace it as soon as possible.
If the water pump is not buzzing, then the pump coil has failed and you need to purchase a new pump.
In case of emergency, temporary aeration can be provided in several ways:
– Fill the air mattress, car chamber or something like that with air and use it as an air tank. Then bleed the air slowly, using a clamp to regulate the air flow.
– Using a pump designed to pump an air mattress or car tires, pump air through the filter system every hour for five minutes (this should be done day and night).
– In the medical rubber bag, make a small hole for air to enter it, the tip with the sprayer is attached, as in the previous methods. To supply air to the aquarium, overlap the hole with a finger and squeeze the pear. When all the air is out, open the hole.
– Raise the inner filter so that its outlet is above the surface of the water.
– A water pump powered by autonomous power supply elements (batteries, battery) is convenient not only in the event of a failure of the main air pump, but also in the event of a power outage.
