Filter Max Aquarium Sponge Pre Filters; |
 FILTER MAX; PRE FILTER • 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) . • 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. • Available in three sizes  • A must for HOB (hang on back power filters), such as Via Aqua, Penguin, ReSun or Whisper. These pre-filters retain and improve biological filtration even when HOB filter media is changed. These pre filters also extend intervals between filter cartridge changes, saving money (and contrary to some opinions, improves the efficiency of cartridges by removing more coarse debris before entering the filter, thus allowing the cartridge to remove more fine debris)• Excellent to use with CO2 generators to better diffuse CO2 into the aquarium (you use these filters to diffuse the CO2 bubbles into the aquarium) (Click on picture to the left for larger view)  *Filter-Max I:Sponge size 2 inches by 2.75 inches Tank size: up to 20 gallon Surface area: 30.6 sq. in.
