Mechanical
Filtration:
Ø
Filter floss: removes solid particles from the
water, has to be changed every 1-2 weeks.
Ø
Sponge: beneficial bacteria will settle on the
filter media.
ü
Here we employ the sponge & wool
as media to trap the waste materials.
q
Chemical
Filtration:
Ø Active carbon (removes foul smell)
Ø Algone (Prevention of algae outbreaks triggered by high nutrient levels)
Ø Zeolite (removal of nitrate/nitrite/ammonia- will disrupt biological cycle)
ü
Here we have the activated carbon to
reduce the amount of foul smell.
q
Biological Filtration:
Ø Beneficial bacteria: Transforming ammonia to nitrite, and nitrite to nitrates.
Ø Bacteria thrive on stones, gravel, filter media, sand, bio-balls with a constant good supply of oxygen.
ü Here the beneficial bacteria grows on the sponge, floss, bio-balls. (takes about 2 weeks to grow initially)
