BIO-FILTER MEDIA
BULK PVC STRAND MEDIA

Of all the different types of media available on the market today, PVC strand media has been proven to the the most efficient for both it’s ability to provide massive surface areas for bacteria contact with the water and also it’s ability to be cleaned when necessary. Closed media materials such as plastic blocks, shot gun wads and others are almost impossible to clean because the particulate clogs all the pores and then is very difficult, if not impossible, to remove.

In a properly designed biofilter the water can be slowly moved through the stands containing the denitrifaction bacteria without restriction allowing 100% of the surface area bacteria colony to have access to the ammonia and nitrites.

PVC strand biofilter media from Global Aquatics works perfectly in both horizontal bio-filters and up-welling types. Providing a high surface area per cubic foot (250 sq. ft.) strand media allows lots of room for easy water passage past the denitrifaction bacteria. When it is time for the media to be serviced it is easily removed to be gently washed down to remove solid particulate accumulation and then replaced, still charged with the bacteria for immediate resumption of the filters task of removing ammonia and nitrite.

Global Aquatics strand PVC media is sold by the compacted cubic foot. When it is first placed in the biofilter is will seem to be more than a cubic foot but it will settle down after water is added and the bacteria begins to accumulate on it. It can be placed in the biofliter and allowed to charge itself over time or Global Aquatics bacteria extract can be added to speed up the bacterial colony growth.
