If you want to keep your water looking clean, then we recommend using Bio-Foam Max on the red pre-filter basket as it contains 30 percent more area when compared to the white Pre-Filter Bio-Foams that come included with the filters. Since beneficial bacteria will also grow on the blue foam, the biological filtration will also be increased. (Note: you can only place the Bio-Foam Max on one side of the pre-filter basket). Fluval recommend you rinse the BioMax Rings monthly and replace them every six months. Based on our own experience, however, you don’t need new rings until the old ones completely breaks apart. Regular rinsing should be enough to keep the rings effective for many years. My only concern is the micro-pores in the product may easily get clogged up with crap and therefore making the product less effective. Fluval suggests that you place the Ammonia Remover at the top grey media basket of the 106, 206, 306, 107, 207 and 307 canister filters. With the 406 and 407 canister filters, you can use either of the top two media baskets. Make sure you rinse this media painstakingly before putting it into you filter. In the end, it’s important to realize that all nitrate removers essentially do the same thing. As long as they’re safe, you won’t make a bad decision regardless of which product you choose.

You should replace the Ammonia Remover every month as it will lose its effectiveness over time. You can also swap them sooner (or later) based on what your test kit show. Don't go for ammonia or phospharte removers (or any of the other removers), they're a chemical solution (generally), and for what is taken in, something is usually released instead. As for ammonia removers, they're free and build themselves up when cycling the filterhttps://fluvalaquatics.com/us/product-category/filtration-media/media/external-media/filtration-media-media-external-07-series/?product_count=36

You can place the carbon in the very top grey media baskets of the 106, 206, 306, 107, 207 and 307 in addition to either of the top two baskets of the 406 and 407. Make sure you meticulously rinse the carbon before using it in your filter. Other than being an extremely effective nitrate remover, Seachem Matrix is also very safe for your fish as it is made of 100% natural volcanic ash. It will not alter the pH of your water or leach any unwanted chemicals, making it a great choice for those who are looking for a natural solution.

Different types of filter media are capable of catching many types of these impurities, and it is important that you choose a nitrate remover that aligns with your specific requirements. SafetyYou should replace the pads every three months. With that said, if you notice a reduction of the water flow due to the micro-­fine polyester being clogged up with fish wastes, then you can replace polishing pads earlier than the recommend time. You should replace the ClearMax on a monthly basis. Of course, you can adjust depending on what your water test kit is showing.
