Aquarium Sponge Filter | ATI-AAP |
Replacement Hydro Sponges

COMPLETE Line of THE BEST, Patented HydroSponge Filters (Originally from Lustar)

Superior to ALL OTHERS for Biological and Mechanical Aquarium Filtration.

Now Distributed by AAP (original design by Lustar, Patented by ATI)
AAP is the LARGEST AUTHORIZED dealer for the patented ATI Sponge Filter, selling unique models and parts not found at other non authorized dealers.
Why purchase anywhere else since they also have been a major supporter of this hobby for decades including copious amounts of FREE information?

As well these are American (USA) made with as much as 5 times the capacity of a given sponge size over Chinese knock offs, why purchase outside North America for an inferior product to save maybe $1 to $2?

• Capable of moving more water than other sponge filters.


• One inch diameter lift tube allows for high volume water flow and allows use of power head without adapters.
  All sponges are 1" inner diameter (which may stretch to 1.25" inner diameter")


• Raised off bottom, no dead space.


• Heavier base.


• Can be used in the vertical or horizontal position.


• Easy to clean. Just rinse and squeeze in used aquarium water (never tap water).


• Made from Proprietary Patented Sponge Foam for the highest mechanical debris capacity and bio capacity; generally as much as FIVE TIMES THE CAPACITY of other non Patented Sponge Filters!!!
  As well, patented reticulated filter foam (PRO) foam for higher flow rates. We also have the combo sponge filters that combines the best of both the standard & reticulated sponges.
  
  NO other sponge filter compares! Even the "Deep Blue Sponge Filters" & others who have infringed on the modular design patent of the Hydro Sponge Filter still do not have the same high capacity sponge! The proof is in how many more rinsings it takes to clean an AAP/ATI Hydro Sponge Filter over ALL OTHERS due to the much higher capacity!
