![]() A downside is that the sand will eventually compact which will restrict airflow and it could reduce oxygen levels in the tank. The benefit of this type of filter is that it provides great surface area for beneficial bacteria to grow. ![]() In order to facilitate filtration, you will probably need to buy a separate power filter or pump – most fluidized bed filters do not come with one. Fluidized bed filters work by pumping tank water into the filter, forcing it up through filter media consisting of sand, silica chips, or plastic. The most notable difference is the fact that these filters hang on the back of the tank. Over time, the bio-material inside the wet/dry chamber becomes dirty which eventually leads to a build-up of unwanted nitrates in the aquarium and, as you should know, nitrates are not reef friendly! If you perform routine maintenance on your wet/dry filter, however, and keep up with your regular water changes, then this might not be a problem.Ī fluidized bed filter differs from canister filters and wet/dry filters in several ways. Often referred to as nitrate factories, many aquarists believe that wet/dry filters are suitable for fish-only tanks but not reef systems. Though there are many benefits to using wet/dry filters there are also some downsides that you should consider. Extra equipment like protein skimmers also play an important role in maintaining good water quality in a saltwater tank. The most popular types of filtration systems for saltwater aquariums include canister filters, wet/dry filters, and fluidized bed filters. Each system has its own unique set of benefits and disadvantages, so keep these things in mind as you consider the needs for your saltwater tank. With all of this information in mind, you should now take the time to learn about the differen types of filtration systems available for saltwater tanks. ![]() The most common form of chemical filtration is the use of activated carbon. Chemical media placed inside the filter can also remove Phosphates, Nitrates, Ammonia and many other toxins. that can cause odors and discoloration of the aquarium water. These media removes dissolved waste materials such as fish waste, etc. This is achieved through the use of various media or resins placed in the filter. To achieve the desired results in your own saltwater tank, the three different types of filtration should be used in combination. Now that you’ve learned the basics about the different types of filtration, you should be able to see how all three of them combine to create an effective filtration system. ![]() If the system is not in place, the biological load of your tank could be too high for the beneficial bacteria to accommodate and, as a result, ammonia levels will spike and your fish could get sick and die. In order to ensure a safe and healthy environment for your fish, you need to establish a biological filtration system in your saltwater aquarium before you add your fish. Another name for biological filtration that you might be familiar with is “cycling” or the nitrogen cycle. The process of Biological filtration does not happen fast – it usually takes between four to six weeks to be established. Biological filtration is the process in which beneficial bacteria convert organics that have been broken down into the toxic elements of Ammonia and Nitrite into the less harmful compound Nitrate, which can then be removed by water changes or chemical means. A biological filter is a living entity that takes in oxygen and unwanted substances from the water. Rather, biological filtration systems consist of nitrifying bacteria that help to break down wastes in the aquarium. The third type of filtration is very different from the other two because it doesn’t involve any actual filtration in the literal sense.
