Introduction to homemade fish tank filters There is a good filtration device in the fish tank,Only by keeping good fish and changing less water.First, the filtering methods mainly include physical filtration, biological filtration, chemical filtration, etc.Two, there are many types of filters in the form of filters,For example, air lift biochemical cotton filter, bucket external filter, top filter of aquarium, fish tank filter with shape, etc.1. air lift biochemical cotton filter sucks biochemical cotton into the upper air pump or water pump without bottom connection,The flow of gas in the water drives the flow of water to circulate in biochemical cotton.The residual bait, biological excrement and other organic substances in the water can be absorbed on the surface of the sponge.Advantages of gas lift biochemical cotton filter: simple structure, low unit price,Use it directly in the fish tank water.Disadvantages: the filtering principle is simple and the effect is poor,Clean bi
What's the matter with the pool water filtered through the sand tank? Physical and chemical aspects of your problem, the physical point of view is that the accuracy of your filter is not high enough to filter the larger particles in the water, but the smaller suspended particles are still in the water, so how do you filter them? this requires checking if your sand tank is less sand, or if you don't have enough time to open the circulation filter.There is a range of sand cylinder filtration accuracy. it can't be said that the mud water can be filtered through the sand cylinder. it is impossible. You can add a precipitation agent to the water for auxiliary clarification,In chemistry, too high the pH of the water can also cause the pool water to look turbid. Of course, the water quality is bad. it also seems that the pool water is turbid. Judging from what you are talking about at present, if you don't deal with it quickly, your pool of water will deteriorate, or it will be scrapped.
