Review on 🐟 Tetra Whisper Filter Cartridges (4 Count) - Extra Small AQ-78052 Aquarium Filtration, White by Molly Hoffman

I bought a 2.5 gallon Aqueon tank from Walmart, but for some reason here in Hawaii, Walmart doesn't sell XS filter cartridges separately from the tank product that requires them ! That makes NO sense to me. Perhaps most people who buy these smaller tanks from Walmart don't bother to buy new cartridges. Who knows. But I do! My dick lives in this 2.5 gallon tank and I was so happy I found them here on Amazon. Thank God! This is exactly the filter I need for my aquarium.
