How To Choose And Care For The Sponge For Filter Aquarium

For any aquarium, quality water filtration is important. A significant role in the device Fish Tank Filters occupy fillers.

There are many types of fillers for Fish Tank Filters, among which the most common is a sponge. Almost no filter can do without this filler.

What is it?

Sponge – an effective filtering material and filler for Fish Tank Filters, which provides not only mechanical, but also biological water purification, can be represented in the form of a cartridge and is made of special foam rubber.

Advantages and disadvantages

The sponge has a porous structure, mainly used for mechanical filtration of water in aquarium. Over time, colonies of beneficial nitrifying bacteria involved in biological water purification are formed in its cells. When it organic matter, formed from the decomposition of the waste products of fish, rotting plants and food residues, goes into an inorganic state.

Such a filler is not expensive, used in many models of internal and external Fish Tank Filters, it can be washed and used repeatedly.

The disadvantages of this filler include not high cleaning efficiency. compared with other materials, as well as the fact that over time, elasticity is lost and replacement is required.

Which one to choose?

How To Choose And Care For The Sponge For Filter Aquarium

Filter sponges differ in pore size: small-, medium-, large-porous.

Small pores are designed for better filtration of aquarium water, clogged more quickly with debris and dirt, which requires frequent washing and, in the future, faster replacement.

Large pores are suitable for filters with an increased workload, they require less frequent maintenance, but they retain mainly large-sized garbage, which reduces the cleaning efficiency.

Therefore the choice it is better to stop on the lips of small and medium porosity, which will help to make the water in the aquarium cleaner and more transparent. It should be remembered that the greater the volume of filter material, the more efficient the filter.

How to care?

Do I need to wash / clean?

The frequency of washing the sponge filler depends on the volume of the aquarium and on the number and types of fish. So, for example, because of the fish digging through the soil, the water becomes cloudy faster, and the filter becomes clogged with dirt in a shorter period. On average, the sponge should be washed once every two weeks, in a herbal aquarium – once every two months. Over time, each aquarist begins to understand when washing the filter with such a filler is required.

How to rinse?

  1. Disconnect the filtering device from the electrical supply (for a short period) and pull it out of the aquarium, disassemble it.
  2. The sponge must be carefully removed from the filter.
  3. Place in aquarium water at room temperature, drained when changing water, rinse.
  4. Do not use any cleaning products so as not to eliminate the beneficial microflora.
  5. Do not boil the spongy filler.

It is important to know that the beneficial bacteria remain alive in the sponge only when the filter is running, and after it is turned off, left without oxygen, die for 3 hours, and when it is turned on again, they end up outside the filter, in water. Fish may die breathing the remains of decomposed microorganisms. Therefore, after turning off the filter for a period of more than 3 hours, the sponge must be washed.

Do I need to change?

If the sponge begins to creep away or even fall apart into pieces, it is necessary to replace it.

This usually happens in 3-4 years of using a filtering device; otherwise, the efficiency of its operation will fall, which will affect the quality of water in the aquarium and, ultimately, can lead to the death of the inhabitants of the aquarium.

When changing the sponge do not need to be afraid of the complete disappearance of beneficial microflora in the aquarium, as much of it exists in the ground, but only if it has been at least two months since the construction of the aquarium, because during this period the established nitrogen cycle in the aquarium becomes stable.

Step-by-step instructions for replacing the sponge can be seen in the video below:

Alternatives

There are a number of other fillers for Fish Tank Filters:

  • synthetic winterizer;
  • ceramic fillers;
  • plastic biochars;
  • glass ceramic fillers;
  • fillers from lava and expanded clay;
  • zeolite;
  • peat;
  • activated aquarium carbon;
  • Tetra BalanceBols.

Sponge, as one of several types of fillers for Fish Tank Filters, possessing not a high price, participating in mechanical and biological water purification, with timely washing or replacement will ensure effective filter operation, thereby creating a quality habitat for fish, which will undoubtedly please their owners.
