Marineland Carbon Bags, 2 Count, Support Chemical Aquarium Filtration, Rite-Size S, T and X, Fit All C-Series and Magniflow Canister Filters

These are hard to find in your pet stores, so I just buy them here on Amazon. The price is about the same either way.

I encountered difficulties with cloudy water in my 10-gallon betta tank. Despite trying various filters, I found no success. By chance, I came across this product and opted to test it out. Remarkably, within less than 24 hours, the clarity of my betta's tank improved by 50 percent. It is essential to adhere strictly to the provided instructions prior to utilization.

Nothing.
