Filtration in your fish tank is incredibly important. Without proper filtration, debris and toxins tin build up leading to devastating consequences for your fish. The importance of filtration might be clear, but what isn't, is how often y'all should change your fish tank filter. The answer depends on which type of filter.

The actual filter itself – which holds the media – won't demand replacing unless it stops working. Mechanical filter media volition not need replacing until it starts to autumn apart (in fact, replacing information technology will do more harm than good), however information technology will need rinsing once every month or so in tank water. Chemical filters will need to be replaced nearly once per month. Biological filters won't need replacing until they fall apart, simply you will want to rinse them once per month in tank water.

Mechanical Filters

Mechanical filters force the water through media such as a sponge to remove solid debris. This helps to keep your water clear and fish tank clean. The filter itself will not demand replacing unless it stops working, and equally long as the filter media is not falling apart, information technology won't need replacing either.

In fact, there are negative consequences to replacing the media in a mechanical filter. Beneficial bacteria that acts equally a biological filter will build upwards on the media, and replacing the media will completely remove this bacteria from the tank.

Eventually the filter media will start to clog up and you will demand to rinse information technology. You should exercise this about in one case per calendar month. It'southward a good idea to combine this with a water change and so you can use the tank water to rinse the media. This will aid to keep as much bacteria as possible on the media. You can besides rinse information technology in conditioned h2o, but do non rinse in unconditioned tap water.

If the filter media starts to fall autonomously, it will need replacing. When you lot outset using the new media, leave the one-time media in the tank for a few weeks to requite the new media time to build up bacteria.

Chemical Filters

Chemical filters are used to remove impurities from the water. Carbon is the nigh common media used. With chemical filters, the media adsorbs particles and volition somewhen fill up up and go saturated. Chemical Filters volition need to be replaced about once per month, or at least once every two months.

Biological Filters

Biological filtration occurs all over your fish tank. Benign bacteria breaks downwardly ammonia into nitrites, and so nitrites into nitrates which are much less toxic. This bacteria will grow all over your fish tank, especially in the gravel and mechanical filter. You can also purchase biological filters which just human activity every bit another identify where bacteria can easily grow. You won't demand to modify a biological filter until it starts falling apart, but you might want to requite it a rinse in tank water every month or so.
