The frequency of replacing fish tank filter cotton and how to choose a medium efficiency filter

How often is it appropriate to change the fish tank filter cotton?

Firstly, do not assume that the cleaner the fish tank filter cotton, the better, and do not vigorously wipe it. Fish tank filter cotton is the place where physical filtration is dense in the filter and where digestive bacteria multiply and grow densely. Therefore, it is recommended to clean the filter cotton less, only half of it should be cleaned each time, and the other half should be cleaned again the next time. When cleaning, use clarified water from the original steel cylinder, do not use cleaning agents, and do not use hot water, as this will inhibit or damage the digestive system.

And don't frequently replace the fish tank filter cotton, which is also a home for digesting bacteria. You can replace it according to the situation. If the residue accumulates for too long, it will also affect efficiency. It is recommended that your fish tank filter cotton is really unusable (the filtering effect is obviously not good) before replacement. Also, activated carbon will change the pH value of water, affecting the growth of beneficial bacteria, so don't use it unless the water has an odor.

A fish friend told me that his cotton was too dirty and overflowed. Then he took a bucket of water obtained from the raw water in the fish tank, twisted it with his hand, and washed away the surface dirt. I think it's good, but in fact, he just washed some fish attached to the filter cotton in the fish tank and enhanced its permeability.

How to choose a medium efficiency filter? What are the main factors?

Medium efficiency filters are very common in the use of central air conditioning units, especially in centralized air supply systems, which are equipped with some primary filtration systems. The market demand is still high every year, and the key to choosing a medium efficiency filter includes many aspects, such as parameters such as excess air volume, dust volume, and whether test data meets industry standards.

Turning off the maintenance effect of the intermediate filter can better utilize the function of the next filter. If cleaning is not required, the F8 intermediate filter can also be used. In addition to being used in ventilation systems, it will also play many roles in the pharmaceutical and food industries, thereby increasing the front-end filtration capacity and extending the service life of the end high-efficiency filter.

Understanding equipment requires attention to many aspects. Firstly, from the perspective of type and structure, it can be divided into two types: frameless and framed bags. The composition of the filter material is also different, some use non-woven fabric and some use fiberglass. People can compare the product structures of different manufacturers and choose the equipment with high cost-effectiveness. For medium efficiency bag filters, there are two types of structures: frameless and framed.

Not only that, the medium efficiency filter can also serve as a front-end filter, which has a significant effect on reducing the load of high-efficiency filters. Due to its large windward side and low wind speed, it enjoys a good reputation in the market.

In order to ensure the effectiveness of medium efficiency filters, many new devices have been developed to improve their products. Some manufacturers use cold plate spray frames, while others use galvanized plate frames. As for the selection of filter materials, it is more diversified and non-woven fabrics and glass fibers can be used. These types of filters have relatively wide sizes, usually about 1-5um. People can judge the effectiveness of the filter by colorimetric method. Filter materials are divided into different types, and we can compare and choose them.

That's all for today's introduction of fish tank filter cotton. Thank you for watching. See you in the next episode.
