Review on Fluval ClearMax Phosphate Remover: 100g Nylon Bags, 3-Pack, A1348 for Crystal Clear Aquariums by Erin Hawkins

As advertised this filter makes the water really crystal clear. As a beginner in aquariums, I still have some "problems" to deal with, such as: B. high nitrate levels and little algae growth. However, you will NEVER realize that I have these problems by looking at the tank. The water is crystal clear. The only downside is that these cases are a bit large and difficult to fit into some of the media bays. For my 25 gallons of 6 fish with a grainy black substrate (which can often cloud the water) this filter lasted at least two months with 20% weekly water changes. Pros: - Works well, keeps crystal clear water. Money. Cons: The media pockets are about 2 inches larger than I like, making it difficult to fit comfortably in the media bay. However, I got it working!
