ATI Hydro Sponge PRO Filter Size #4 Coarse - For Aquariums Up To 80 Gallons - Made In USA
About this item
If you keep aquariums, you probably know ATI sponges.
This is the Hydro Sponge PRO, size #4, with coarse pores.
It's rated for tanks up to 80 gallons, so it's a decent size for medium to large freshwater or saltwater setups.
It's an internal filter, meaning it sits inside the tank, usually powered by an air pump.
The sponge provides mechanical and biological filtration—good for fry tanks, hospital tanks, or as a supplement to your main filter.
Made in the USA, so quality is solid.
It's brand new in original packaging.
The UPC is 7 32549 00940 3 if you need it.
Coarse sponge means it won't clog as fast, so it's lower maintenance.
Perfect for breeders who need gentle flow, or for tanks with heavy bioload.
Just hook up an air line, adjust the flow, and let it do its thing.
Easy to clean—just rinse in old tank water during water changes.
ATI sponges are pretty much the gold standard for this type of filter.
Size 4 is versatile and should handle most community tanks in that 40-80 gallon range.
