What type of biofilter bin is more favorable for microbial growth in a fish pond filtration system?

In a fish pond, we keep not only koi, but also hundreds of millions of microorganisms. Of these, the beneficial water-cleaning microorganisms have a decisive influence on the overall water quality. Water-cleaning microorganisms need a breeding ground in which they can thrive, and the Biofilter provides the best environment for them to do so.

The setup of biofiltration bins can be considered crucial, and it can be said that the pool water really enters the stage of purification and reduction of water quality after flowing into these biofiltration bins. Currently, biofiltration bins are often designed as multiple interconnected units for the purpose of biological filtration.

☞  why?Why have multiple interconnected biofilter units?

As we know, the main function of the biofiltration silo is no longer to block solid wastes in the water, but its main function is to purify and restore water quality using water purifying microorganisms attached to the surface of the filter media. These microorganisms can only maintain their own vitality and function in flowing water, and multiple interconnected biofiltration units should prevent the biological failure of part of the filter media caused by the emergence of stagnant water areas.

In addition, biofilter chambers are often equipped with a variety of filter media with different characteristics and properties - such as bacterial houses, coral stones, filter cotton, biochemical felts, zeolites, biochemical spheres, ceramic rings, nano-bacteria cultivation rings, and so on. And multiple interconnected filter chambers can be placed separately in a set order, while ensuring that oxygen can be adequately supplied to all parts of the filter media to enhance microbial activity.

Finally, when we clean the fish pond filtration equipment can not be cleaned all at once, so as not to cause large fluctuations in water quality due to the large loss of water purification microorganisms. Therefore, divided into a number of interconnected filter bins can be a good solution to this problem, to be cleaned can be cleaned every half a month respectively, so that you can maintain the number of microorganisms throughout the filter and the relative stability of water quality.

☞ What do I need to be aware of when designing a biofilter silo?

1The water in each chamber flows through the biofilter media from the bottom up.

Allows solid wastes remaining in the water to rest more on the bottom of the chamber than on the filter media, and facilitates bottom draining and backwashing to clean the filter media.

2, leaving enough space for settling dirty

Leave a minimum amount of space from the filter support to the bottom of the chamber in each chamber20cm+ space to facilitate settlement of residual solid waste.practiceOn, as long as conditions permit.The greater the height and volume the more favorable will be the effect of settling.

3, the whole system built-in oxygenation device

The performance of each kind of filter media are not the same, we should start from their own actual situation to consider the specific use of which filter media. If the water quality is somewhat acidic, more coral sand as a filter material, and zeolite has a special effect of absorbing ammonia and so on.

Or the old saying: fish first raise water! Good water produces good fish. The beauty of koi lies in nature, how can koi exude natural beauty in toxic water? I hope everyone can raise koi with clear water and enjoy a good life!
