Using the Fluval Poly/Carbon Cartridge is a breeze. First, pick the right size for your filter. If you have a Fluval U2, go for the 'U2' cartridge, and so on. Then, simply insert the cartridge into your Fluval underwater filter according to the instructions that came with your filter. As for the water environment, it works great in freshwater, marine, or reptile setups. When it comes to maintenance, check the cartridges regularly. If you notice that the water flow is reduced or the water doesn't look as clean as it should, it might be time to replace the cartridges. Usually, you'll want to swap them out every few weeks, but this can vary depending on your tank size and the number of inhabitants. And remember, keep your cartridges dry and in a cool place when not in use to make sure they stay effective.
