How does the external fish tank filter increase oxygen supply? The external filter bucket has no oxygen enhancement function.External filter,If you don't use a three-in-one submersible pump, there is no oxygen increase.If you don't see oxygen,There may not be this feature,It may be that the connection and placement are incorrect,No picture can be accurately judged.The contact surface between the water surface and the air is also undergoing continuous oxygen dissolution,Photosynthesis of aquatic plants is also undergoing oxygen dissolution.This is how the oxygen in the water comes.Whether fish will die without oxygen depends on whether the dissolved oxygen content is lower than the physiological requirements of fish.With the volume of water,Surface area,Feeding density, water flow,Temperature and temperature,Atmospheric pressure,There are many factors related to plant conditions.For a simple analogy,A two-meter-long fish tank keeps a small goldfish,Even if you don't have any equipment, you won't lack oxygen,

What water to use for the sea water, do not want to buy water purifier Configure seawater as long as the artificial seawater salt is mixed with water according to a certain proportion,It can be matched with artificial seawater that is close to natural seawater.Among them,Domestic sea salt contains 20 trace elements,Imported sea salt contains 40 trace elements.Water sources prepared by artificial seawater,Non-toxic should be selected,Tasteless,Clean filtered water,Groundwater and tap water for a week.The density of artificial seawater for breeding should be maintained at 1.022-1.023,Density of seawater,The salinity and water temperature change at all times,At a certain temperature,The sea water required can be prepared according to the data in the table.For example, when 100 kg is 25 degrees Celsius,The density to be formulated is 1.The artificial sea water of 021 needs Sea salt 29.9G.Do not use metal containers in the preparation process of artificial seawater.The artificial seawater just prepared is relative
