The listing, NIP Aquarium Filter has ended.
New in package. Aqua-Tech EZ change replacement filter cartridge.
Fits 20-40 gallons & 30-60 gallons.
Fast, clean & easy. Aqua-Tech filter systems take the guesswork out of changing your filter cartridge. Since all Aqua-Tech filter cartridges come pre assembled, there are no messy carbon pouches to deal with. Just remove the old filter cartridge & place a new one in the filter.
I accidentally grabbed the wrong one at the store. I hope someone else can use it.
I ship next day ( excluding weekends & holidays). Shipping is always free.
