A water filtration system is essential in order to keep your fish tank healthy, whether it's a tropical paradise or a freshwater set up. The purpose of a water filter is to remove excess food, decaying organic matter, dangerous chemicals and fish waste products. This regular upkeep means fewer water changes and maintenance as you have a cleaner tank for longer. If the waste and debris are not removed, not only can the tank look dirty, but there can also be a build-up of harmful toxins which can be dangerous to fish and plants living in your tank.
There are three main methods of filtration: biological, mechanical and chemical, and at Real Aquatics, we stock a wide range of aquarium filters which have been designed to hold all three at once. In order for your filter to do its job, you'll need to buy aquarium filter media to put inside. Using the three together ensures the clearest, purest water, and as such, a healthy tank.
Whether you're after an internal filter to sit inside your aquarium or an external filter to sit outside, there are a wide variety to choose from.
