Just got some fish and instead of buying from the pet shop, went with Chewy. They are great and always go there first to purchase all my pet needs!
Great Filter Cartridge

Convenient Cartridge Filters, 2 to a pack with awesome price. Although the filter doesn't work all that great with the tank it came with.

Useful Small Filter
on Jun 12, 2018
I use this small Whisper filter cartridge for both Whisper 3i Power Filter and Azoo Mignon 50 filter (diagonal fit,). It is a good little filter pad, but due to small size needs cleaning a little more often than larger sizes.

Cartridge fills up fast, cant really say anything about them in a positive or negative manner its a filter cartridge.

Easy Filter Changes for Small Tank Aquariums
on Oct 19, 2017
I think these are made for the smallest Tetra Whisper filter. But, they are so easy to change! No parts to save, nothing to measure, add and assemble. You just rinse the new filter then pinch, pull and toss the old one. Put the new one into the same place and you're good for another month or maybe longer. Tip for clearest water: Avoid doing your 20% water changes, your cleaning and your filter changes all at the same time. That way useful culture remains to help clear the water of your aquarium.
