Review on 🐠 Tetra Carbon Filters: Perfect Fit for Whisper EX Filters in Aquariums by Wendy Roney

Pathetic shameful mess! After a horrible experience with these filters, Tetra Revain have finally supplied a decent replacement box and it has soothed my anger so far! It's time to buy a replacement and be shocked again to see those poorly made and packaged filters! What's up with Tetra QC and what the heck are you willing to wear to make a quick buck Revane!? These filters can't even filter light!Previous ReviewWhat happened? From high quality filter cartridges that typically last over 2 months to poorly/cheaply made cartridges that literally came out of the box with charcoal leaks! See my photos of a new, unused, finished filter with a layer of fiber so thin the embers spurt out. I've also included a comparison photo of my old filter, huge difference in quality. Also, the fiber material from a recently purchased product was so thin that light could see through it. Carbon particles will seep out of the cartridge into the box, making a huge mess and rendering the filter useless. To make matters worse, all three boxes (that's twelve filter cartridges) are of disgustingly poor quality. What happened? Absolutely not recommended! Zero stars if possible.
