🐠 Tetra Whisper Large Aquarium Filter Cartridge 3pk: Clean and Clear Aquarium Water Guaranteed Review

Subtle and convenient already assembled and that's it. I've been ordering them for over a year now. Judging by recent orders, the quality has deteriorated. There were several filters that had almost no carbon.

So what I order and what I get are two different things. I chose the more expensive one because I realized there was something better out there. I paid $24 for a 3 pack and paid $4 for what I got. Heck I could pay $13 for 6 of them. Very, very unhappy at the moment.

I change filters monthly and they are very easy to change. They fit my topfin filter and the only problem is getting them to fit the grooves properly, but that's not a problem for me. Changing the filter only takes about 3 minutes and my aquarium stays clean. I have an algae problem and it's not helping, so I'm rating it 4 stars.
