Review on 🐠 Enhance Aquarium Filtration with Top Fin Element Filter Cartridges by Claudia Garza

I can't understand why these weak filters are so expensive. The feeling is like the baby wrapped charcoal in a plastic frame with a cotton swab. Haven't found a suitable alternative yet, but they're at least three times more expensive than my 20 gallon AquaClear Fluval filters, which are much better made and last much longer. I will not buy this brand again.
