Review on 🐠 Enhance your Aquarium Filtration with REEF Red Sea SPEC Carbon! by Michelle Dreger

I bought this for my 100 gallon saltwater tank. I put some in the filter bag that came with it and placed it in the sump in a spot where water could flow onto it. In less than 10 minutes my whole tank started looking cloudy. After 1 hour my entire tank was basically black and I couldn't even see the back of the tank. I bought it because it had good reviews for being low in dust. I'm not sure if I had a bad batch or just didn't flush it properly, but it basically messed up my tank and I had to start over because it wouldn't go away after two days of filtration. If you buy this product, just make sure you wash it thoroughly over a long period of time.
