Filtration is done in three ways;
1 Mechanical filtration-It involves the use of fine material. For this case,it is usually a32 sponge or a piece of cloth made of polyester.The sponge and polyester cloth prevents solid particles from entering the filtration areas.It also helps to keep the water clean.
The challenge with mechanical filtration is that,the filter needs to be cleaned regularly,after one or two weeks. Letting the solid particles to pile up causes your nitrates to get too high that it may make your fish to be sick.
2 Biological filtration– This filtration provides room for the growth of good bacteria which reduces the toxins produced by your fish.The bacteria keeps the fish safe in the water changes.Failure to use this filtration type results ammonia and nitrate spikes which are poisonous to your fish.
3 Chemical filtration- It uses natural elements to purify the water through the process known as detoxification.This process detoxifies the toxic chemicals as they pass through it.
Chemical filtration is recommended for use when adding small fish to to the tank or bowl where either ammonia or nitrites levels can be concentrated.
The method used in this filtration is by use of charcoal which removes tannins in the water that may cause brownish discoloration.
Carbon does not remove nitrates.It deactivates the hormones of the fish in the water.
