I’ve used this carbon in my 50-gallon freshwater tank for three months. The water has become much clearer and the fish seem more active. No fish deaths or odd behaviors since adding it to the filter.
Colin Rutherford –
Works well for removing odors and discoloration. I noticed a noticeable improvement in water clarity after two weeks. I plan to use it regularly in my new tank setup.

Great product for maintaining clean water. My saltwater tank has been running smoothly with this carbon for over a month. The filter performs better and the water smells fresher.
