An internal sponge filter is a type of filter that is placed inside the pond or aquarium. The filter uses sponges to remove impurities and debris from the water. Sponges are porous and absorbent, meaning they can trap pollutants in their pores. The water then passes through the sponge and back into the aquarium, cleaner than before. Sponge filters are an inexpensive alternative to other types of filters, but they do require regular maintenance.

The disadvantage of an internal sponge filter is that it cannot be used if you have an external power supply or if there isn’t enough room in your tank for an additional piece of equipment. You also have to replace the sponges every few weeks or so because they get dirty after a while and stop working properly.

The Internal Sponge Filter works in aquariums up to 30 gallons and is easy to install and maintain. Filtration begins with an air pump that draws water through a sponge, which traps particulates. Different models come with varying amounts of sponge, but all are simple to clean, simply remove the filter from your tank, rinse the sponge under running water—no need for soap or any other chemical additives—and return it to your aquarium.

Description of Internal Sponge Filter

An internal sponge filter is a small, self-contained unit that filters aquarium water. It is made up of layers of foam and various media, which provide an ideal environment for bacteria to grow and break down organic matter (such as fish waste). The sponge filter draws or pulls water through these layers while it’s running, removing any solids in the process.

A good internal sponge filter will be able to keep your aquarium clean without requiring you to do anything other than plug it in and turn it on. They are simple enough that even beginners can use them effectively with minimal instruction. Most internal sponge filters come with at least three different types of sponges: bio-foam (used for biological filtration), mechanical foam (for mechanical filtration), and carbon beads (for chemical filtration). It’s also common for these filters to include some sort of secondary mechanical media as well–something like diatomaceous earth or crushed coral–that helps remove parasites from your tank’s inhabitants as they’re removed from their environments by the primary foam pad.

Types of Internal Sponge Filter

A biological filter is a tank with a growing medium and beneficial bacteria that break down waste material.

The mechanical filter is a device that captures debris as it passes through the system, preventing clogging and improving efficiency.

A chemical filter removes dissolved waste from the aquarium by passing water through an activated carbon bed, which absorbs harmful chemicals such as chlorine or medications used to treat diseases in fish or plants.

Carbon (charcoal) filters remove odors from your aquarium by absorbing gaseous impurities on the surface of charcoal granules; this process is called adsorption.

Specifications of Internal Sponge Filter

  • Length: The length of the internal sponge filter is 5.5 inches (140mm).
  • Width: The width of the internal sponge filter is 4.5 inches (115mm).
  • Number of Sponges: There are 9 sponges on the internal sponge filter, each with a diameter of 0.75 inches (20mm).
  • The number of Air Stones: There are 6 air stones on this Internal Sponge Filter, each with a depth of 1 inch (25mm) and a maximum diameter of 0.9 inches (23mm). This gives it an air stone count of 6 x 1 = 6
  • The number of Filter Bags: There are 3 filter bags on this Internal Sponge Filter, each bag has 2 different sizes that can be used depending upon your needs and capacity requirements—the sizes are 8x8x12cm or 10x10x12cm. You can use all 3 or any combination thereof according to your requirements.
  • The number of Filter Baskets: There are 9 baskets in total; 8 have a diameter range from 1 inch – 2inch while another one has a diameter ranging from 2-4 inches making it suitable for catching bigger debris particles as well but not recommended if there is any risk for clogging due to lack space available below which could lead into circulation problems when tank water level fluctuates too much causing excessive flow rate which might cause damage due to overload pressure generated during installation time but unlikely though since only happens under extreme conditions like earthquake etc.

Maintenance of Internal Sponge Filter

The internal sponge filter should be cleaned weekly and replaced every 2 months. To clean the internal sponge filter, remove it from the aquarium, wash it with warm water and baking soda or vinegar, rinse thoroughly and replace back in your tank. You can also use an algae magnet to remove any algae growth on the surface of your sponges before washing them in water.

To replace a dirty or non-functioning internal sponge filter, simply remove it from your tank and discard it. Then add a new one back into your aquarium. It’s that easy.

Price of Internal Sponge Filter

The price of an internal sponge filter varies according to the quality, features, and brands. The normal price of the internal sponge filter is around Rs 3,000 to Rs 5,000 (USD 40 to USD 65) in India. In China, the price range varies from CNY 100 to CNY 300 (USD 15 – 45). It’s available at a cost ranging from USD 25-35 in USA and UK respectively.

In Australia & Canada, it can be bought for AUD 160 or CAD 130 respectively.

In Conclusion

To maximize the effectiveness of your internal sponge filter, you must follow these guidelines:

The location should be in the middle or near the front of the tank (depending on what size it is).

You need a good quality pump for optimal results. If you don’t have one yet, we recommend reading about different types of pumps before purchasing so you know which will work best with your new filter. These include submersible and external filters.
