This pre-filter line has been the standard for highest bioload available as a pump pre-filter. Been in the industry for decades! Is the line that started it all for sponge filtration.

These filters are designed with adapters to connect them to water pumps, canister filters, hang on back filters, PVC, and more. There is also another line of sponge filters meant for air pumps or water pumps with bases and lift tubes. Check our other listings.

The correct sponges for the application and the parts required to not get clogged or drop waste back into the water. Adapters to fit most all applications! 

Note: fine filters tend to clog quickly on high flow water pumps. Consider the coarse option or making a combo of fine and coarse filter to make the right filter for your application. Make your own combos with easy part connections!

Details:

• Prevents debris such as dead fish and plant material from clogging the intake by distributing suction evenly down the length of the sponge.

• Maintains the biological filtration when the main filter is changed or cleaned.

• Vastly increases bio filtration capacity over many standard Aquarium Power Filters (HOB filters).

• Can be used with most power heads as a temporary or permanent filter in aquariums, isolation tanks, holding tanks, etc.

• Prevents small or baby fish from being suctioned into the main filter

• Prevents anemone and invertebrates from being suctioned into the filter.

• Traps larger waste particles, mechanically cleaning the water

• Can be used with most outside filters, canister filters and power heads.

• Increases depth of HOB filter intake by up to 6 inches (15 cm.) for better over all circulation (it is still recommended to have more than one independent filter or at least a separate air stone for best over all filtration results).

• Increases longevity of filter cartridges (often by 300% +) of filter the Filter Max is attached to by removing a considerable amount of debris prior to entry into the filter.

• Includes three adapters for use with various main filter intake tubes.

• Easy to clean. Just rinse and squeeze in used tank water

• Can be used in the vertical or horizontal position.
