Review on Highly Efficient Seachem Purigen for Freshwater & Saltwater Filtration by Russell Anh

Looks like a fake. It doesn't even have such an outer packaging as in the product photo (see photo). I used to buy a bag, and these two products are completely different bags with different sizes and packaging. This product leaks tiny particles throughout the tank. The bag itself is thinner and has less pure content. Unfortunately I haven't opened it until now and I think it's a past return window. SAD.
