Biological Filtration Media

Biological filtration needs to fulfill a few simple criteria to be good:

1) They need to have a MASSIVE surface area to volume ratio.

2) They need to be easily cleaned and light weight.

3) They need to remain effective for many years.

The bio balls we sell have the highest surface area to volume ratio. This, in combination with Japanese matting cut to the size of your filter box are great for all medium to large fish ponds. Use the product that aquaculturists use in Australia!
