Review on Aqueon 🔍 Filter Cartridge Replacements by Kathy King

Fits and looks good but I believe these filters contain 10% or less activated carbon than the ones I have used - same make and model so they are not actually made by Aqueon and are counterfeit or they changed the product significantly . The weight of each filter is several times less than the weight of the old ones. I could see a 10% or even 25% reduction in filter media and hope no one notices, but 90% and up? The old ones are heavy, thick, and the entire filter was filled with activated carbon, maybe 1 inch thick, the new ones are a grain/layer thick, covering no more than 40% of the filter surface. The difference between day and night between them, it's hard to believe that they are the same product.
