About this item
- Keep your tank clean and clear with the genuine Penn Plax filter cartridge to fit your Cascade 300 GPH hang-on power filter model CPF5. Sold in 3 pack.
- Activated carbon is great for freshwater aquarium filtration. It has the ability to remove odors, and water discoloration by trapping the pollutants in the pores of the carbon.
- The poly-fiber floss barrier screens out particulate matter and debris keeping the water clean, clear, and healthy.
- No assembly required keeping your hands clean. Easily install into interior compartment of your hang on filter. Suitable for freshwater and saltwater tanks.
- Internal filter cartridge comes in either Blue or Black plastic – and both are identically measured to fit into the Cascade 300 filter tray without any gaps preventing debris and contaminants from passing through back into the water.

Been buying this brand for many years. These filters are on my Subscribe and Save list. A “must have” for PennPlax filters.

Works good. Cleaned my nasty tank up fast after putting it in.

This filter takes your tank from floaters to clear water in a very short time. Works super fast and keeps tank clean! Can’t go wrong! Filter replacements are not cheap but they work great!

The Cascade 300 is the best filtration system there is. My tank is awesomely clear and the fish seem extremely happy. My casualties are few; if any (other than age), because of the water movement and cleanliness the filters provide. Thank you.

We were setting up an old fish tank of ours and had a Penn Plax Cascade 300 power filter but were having the darnedest time finding these filter cartridges in local pet stores but didn’t want to get a whole new unit (this really is a good filtration unit overall, and why spend extra money if you don’t need to?). It seems all the stores carried was for the remote external Penn Plax units (not the hang-ons) but I am happy to have found them here and for a reasonable price.
