Price and Initial Impressions

The MaxClean course sponge filter boasts a surprisingly affordable price point. I purchased mine on Amazon for $9.99 with Prime shipping, a significant bargain compared to many other sponge filters on the market. The initial quality of the sponge itself seemed very good, dense and well-made.

For the price, this filter exceeded expectations in terms of build quality and materials. The size is substantial, offering a generous filtering capacity.

While marketed for 5-gallon tanks and up, its large size might be overkill for smaller setups. This is a point that warrants further consideration.

Size and Suitability

This four-inch by four-inch sponge filter is undeniably large. While suitable for 5-gallon tanks, it's arguably oversized for them. It would dominate the tank's space, leaving little room for decor or other inhabitants.

The filter is better suited for larger tanks, ranging from 10 to 40 gallons. For even larger tanks (55-90 gallons), using two of these filters, one on each side of the tank, would likely be more effective.

It could easily handle a well-stocked 40-gallon breeder tank. Its ability to serve as a primary filtration system is a key advantage. However, it's also great for smaller tanks as supplemental filtration, providing extra biological support.

Air Stone Integration and Customization

One significant drawback is the lack of an air stone mounting point in the factory design. The central uplift tube obstructs the placement of an air stone in the standard design.

Several customization options exist to resolve this. One method involves carefully cutting a portion of the bottom to allow for air stone placement. This simple modification improves water circulation and oxygenation.

Another approach is to use the filter without the central tube modification, creating a different filtration mechanism. This method would provide adequate filtration, but with larger bubbles compared to the Air Stone method.

Adding Media: Chemical and Biological

The filter's design allows for the addition of chemical or biological media. By leaving the central tube intact, the space within the filter can be filled with carbon, zeolite, or other filtration media.

This provides opportunities to enhance filtration capabilities beyond basic mechanical filtration. However, care should be taken to ensure the media size does not allow it to fall through the filter's base.

This is a significant advantage, expanding the filter's functionality and versatility to include chemical and biological filtration as well.

Conclusion: A Versatile Filter with Room for Improvement

The MaxClean sponge filter offers excellent value for its price. Its large size makes it suitable for a range of tank sizes, and its ability to accommodate various media types significantly improves its versatility.

However, the lack of a readily available air stone connection is a significant downside, requiring modification for optimal performance. This could be a barrier for some users who prefer a ready-to-use solution.

Overall, the filter is a solid choice for those comfortable with a bit of DIY customization. Its cost-effectiveness and potential for improved filtration make it a compelling option for both beginners and experienced aquarists.
