CRYSTAL CLEAR WATER

This product has been installed in my U4 Fluval internal box filter for 2 weeks now and have noticed a great difference in seeing clearer aquarium water. Has really polished the water and is ideal in reducing algae, phosphate, nitrite and nitrate.

I strongly recommend this product.Read full review
