What cotton is good for fish tank filter cotton, or how to match it? Let's all analyze it briefly together.

Suggest using both bio cotton and sponge simultaneously. If used alone, it is recommended to choose sponge. High density, able to filter cleaner. Filter cotton is a part of the filter, which is a sponge used to filter impurities. The filter surface needs to be cleaned and replaced regularly, so it needs to be replaced every two weeks. The breathability of the fish tank filter cotton should be very good, and the flow resistance of the filter cotton is very small, which can filter many small things. The fish tank filter cotton can be reused, but it must be cleaned with water. The filter cotton is relatively sturdy, the cost is not very high, and it is environmentally friendly. The fish tank filter surface can filter out waste and residue from the water tank, changing the quality of water.

What are the classification levels of fish tank filter cotton? Let's all analyze it briefly together. Primary filter cotton: It can also be used for pre filtering exposed to high dust in the air supply system. Pre filtration and flow equalization filter materials and characteristics of spray system and baking device air supply. Medium efficiency filter surface cotton: (ceiling surface) mainly filters dust particles larger than 1m, generally used for secondary filtration after rough effect filtration, and also commonly used for filtration of plate filters. Efficient filter cotton: mainly suitable for environments with particularly high filtration requirements such as hospitals and laboratories.

The fish tank filter cotton considers two conditions: 1. debris. 2. Cultivate a community of nitrifying bacteria. Several excessive surfaces need to be placed on the upper layer of the first slot. This makes it easier to take it out and wash. The cultivation cycle of nitrifying bacteria is very slow, and the attachments cannot be disturbed frequently. So there is little movement in the later stage. The growth environment of nitrifying bacteria is protected from light by porous materials. These two conditions meet the requirement for a self growing community of nitrifying bacteria. I have dealt with various biochemical cotton, glass replacement, magnetic rings, etc. before. From the terminology used in fish farming in the market, it can be seen that simple filter materials (although the role of good filter materials cannot be ruled out) are equally effective, and the water quality is transparent. Now place 6 layers of filter surfaces on top of the first grid, mainly to review large objects in the water for easy washing. Below, use a thick black sponge. Place the thick black sponge in the second compartment, and the third compartment usually does not have a pump or waste. Cut the black sponge into a 2cm * 2cm square to create maximum space for the attachment of nitrate bacteria. The water quality is good, only the filtered cotton has been washed for 3 years. 1/4 water per week, 380 kilograms of fish tank water, and 120 kilograms of bottom fertilizer water, during which the water pump was replaced. The larger stocking capacity in this environment is one silver dragon (40 centimeters long), one silver coin (35 centimeters long), and one pig nosed turtle (25 centimeters long). If you put food, you need about 150 grams of homemade hamburgers per day. Metabolites can be effectively filtered and broken down by nitrifying bacteria. Adding another turtle, the number of nitrifying bacteria is clearly insufficient to decompose the residual organic matter in the water. The water quality is starting to decline. In the early stages of fish farming, a lot of time and money were invested, but later on, through observing others, I realized that it was important to analyze according to scientific methods. The current result is very simple. In the past, various filtering materials were put in a lot and used very well, but when new fish were introduced, it was easy for large areas of diseases and insects to appear in the fish tank. Now I realize how troublesome it is to have many types of filters. Because wherever there is water, there are sources of disease and insect eggs.
