Question:

Do you need filters and oxygen pumps for small tanks?

Yesterday I bought a small fish tank and raised some tropical fish, but today the bottom of the fish tank has lots of fish droppings, and the water quality looks very muddy. I heard that the filter can play a clear role in water quality But I think the aquarium is relatively small, so the filter should take up many places. Is it necessary for an expert to use these two?

Answer:

No, keep it clean
This requires a filter to keep dissolved oxygen in the cylinder, remove manure, and clean water.The waterfall filter is about 30~50 yuan. Just buy oneOr buy an air pump, with a water fairy can be, only a total of 20~40 blocks
Small tanks require the use of filters and oxygen pumps. This can greatly reduce the artificial burden of feeding. Let's take a look at what these two things play in a small fish tank:1, small fish in normal life will continue to breathe, reduce the dissolved oxygen content in water, in natural waters, because the surface area of water contact with the air, oxygen can quickly dissolved into the water to supplement. But in a small bowl, because the water and air contact area is small, and the feeding density is relatively high, so the content of dissolved oxygen decline will be relatively fast, once dropped to below 3ppm, the fish will continue to float, did not improve the fish will die. Oxygen pumps can increase water contact with air, increasing the rate of oxygen dissolution.2, the residual fish food, fish feces will decompose and decay under the action of microorganisms, forming ammonia and nitrite substances which are toxic to fish. When the concentration of ammonia nitrogen is greater than 0.02ppm or the concentration of nitrite is greater than 0.2ppm. Fish die of poisoning. The filter allows the flow of water to pass through the filter material, so that the nitrifying bacteria on the filter material oxidize the substance to form a basically non-toxic nitrate.If you do not have these two devices we can only rely on water for fish, more frequent to hypoxia and harmful substance accumulation, with these two devices can greatly reduce the frequency of the water, reduce the burden of artificial feeding.
