Newa Aqua Fiber 200g, a high quality synthetic fibre wool for use in all aquarium filters from freshwater to marine. Fiber is an effective mechanical filter media which should be used alongside Biological and Chemical filter media to improve water clarity but more importantly nullify Ammonia, Nitrites and Nitrates. Manufactuered from highly resistant strong fibres able to withstand the most demanding aquarium filtration conditions the Aqua Fiber acts as a highly effective mechanical pre-filter. Collecting larger impurities and debris the Fiber eliminates damaging particles therefore pro-longing the life of any biological filtration. Newa Aqua Fiber has also been produced to prevent it from compacting too much inside the filter, guaranteeing a better flow rate which long term significantly minimises the need for maintenance. For best results why not team up Newa Aqua Fiber with the Newa Aqua Kinishi Sponge for improved filtration. Suitable For: Freshwater. Marine. Reef
