How to Pick the Best Filter for a Saltwater Aquarium.
In saltwater aquariums, there are three basic types of filters: mechanical, chemical and biological. Mechanical filters are the most popular filters because they’re less complicated and less expensive than biological and chemical filters. This doesn't necessarily mean that mechanical filters are the best. In fact, there isn't an overall winning filter. Rather, the best filter is determined by each aquarium’s individual needs.Canister fish tank filters are the most popular option for larger aquariums that can fit 40+ gallons. This is not to say that you can’t find canister filters for smaller fish tanks. As compared to other types of filters, canister filters provide the best biological, chemical and mechanical function. Water is pressurized and forced to go through fine material to trap smaller particles, thus offering superior filtration. They are a great option for aquariums with Koi and Cinchlids as well as plant & saltwater aquariums. The only downside is that been bigger, canister filters often come with a higher price tag.Biological filters create nitrifying bacteria which convert the waste produced by your tank’s inhabitants to a nontoxic state. Biological filters, especially wet/dry filters, are the best option for an aquarium that doesn’t include live rock. The absence of live rock reduces the amount of surface area on which bacteria can grow, which in turn increases the amount of toxic ammonia. In this instance, a biological filter is the best choice because it’s capable of creating the bacteria needed to keep a saltwater tank balanced and livable.With the numerous amounts of saltwater aquarium filters available on the market, it can be a difficult task in choosing the one that is best suited for your aquarium. If you are new to the saltwater tank arena, it will best to consult an aquarium specialist to help you to determine the most appropriate fit. Saltwater fish, corals, and invertebrate possess divergent requirements compared to freshwater fish in the area of water quality. Saltwater tank inhabitants in many cases are much more reactive to low quality water conditions, which can easily lead to harmful bacteria and disease.
