How to maintain and raise arowana fish part 4

Hello my steemit friend !!!!

In this part 4 I will try to review the water filter media which is the most important part for the growth of Dora the beautiful predator ruler of the Borneo river (Kalimantan island).
Steemit friends there are many filter media used. In this part 4 I just discussed the filter used dora.

^{BIO-FILTERMEDIUM}

^{CERAMIC RING}

^{BIO BALL}

The biological filter / Bio-filter medium is a tremendous part of Dora's water filter, although this biological filter media is located at the very end of the water filtration process. Its function is to make the water clear and efficient. This filter media also as a place of life of bacteria that convert nitrites into nitrates. This bacteria also reduces levels of ammonia or dora dung. There are many different types of bio filter media code </ code> with varying prices. The most important thing in choosing this type of media is the amount of cavity sufficient for bacteria in the media even though the cavity will not be visible to our eyes.

^{DACRON COTTON}

^{Busa hitam}

^{Busa kuning}

Foams and dacrons are the first medium to filter out the aquarium faeces before proceeding to bio-media.
