If you want even more mechanical filtration, you can also use the Pre-Filter Media. These rings are designed to filter out medium-sized particles from the water column. You should place the Phosphate Remover in the top grey media basket if you have the 106, 206, 306, 107, 207 or 307. For fish keepers who have the 406 or 407, you can put the pads in either the top two media baskets. Water changing is when the fish keeper will drain a tank from a portion of the water – depending on the percentage of the water change- and replace whatever was drained with clean and fresh water. If you want to remove ammonia from your aquarium, then you might want to take a look at the Ammonia Remover as it uses natural clinoptilolite to absorb the toxic compound from your waters. Fluval suggests replacing the Phosphate Remover pads once a month. You can change them out more rapidly or slowly depending on your water tests.

Seachem Matrix has the lowest detectable phosphate content of all its competitors. This carbon-based macroporous bituminous allows water to infiltrate thanks to its size, large enough not to slip out of the filter bags. Pros 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. Fluval recommend that you clean the Bio-Foam Max monthly and then replace every six months. Based on our experience, you don’t have to replace the foam at all unless it starts to break down. It should remain effective as long as you clean it monthly.This change of mind return policy is in addition to, and does not affect your rights under the Australian Consumer Law including any rights you may have in respect of faulty items.

The Fluval 106, 206, 306, 406, 107, 207, 307 and 407 Filters come with multiple media baskets that filter various unwanted elements from your fish tank water. The Zeo-Carb can be replaced on a monthly basis. With that said, you can adjust the replacement schedule depending on what your water tests show.

You can replace the bituminous carbon every month. You can swap them out earlier if you noticed an increase of the aforesaid impurities. 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).
