Tetratec EX External Filter Media - BB 600/700/1200

Product Description

5 different types of filter media for every type of cleaning 1. Tetratec CR Ceramic Filter Rings remove large particles of waste & help to even out the flow of water through the filter. They can be cleaned with tap water & do not need regular replacement 2. Tetra Tec BF Biological Filter Foam doubles as a media for removing finer particles of solid waste as well as providing a high surface area for bacterial activity. To operate the foams purely as a mechanical media for solid waste removal clean them under tap water as necessary. To maximise their biological activity clean them in a jug of aquarium water 3. Tetra Tec BB Bio Filter Balls are biological media that provide an excellent environment for friendly bacteria to break down ammonia into harmless nitrate. Because they are not too porous they allow a good flow of water through them which ensures that all the bacteria receive a supply of oxygen & nutrients. This keeps them working effectively & avoids ¿dead areas¿. Clean in aquarium water only as & when necessary 4. Tetra Tec CF Carbon removes organic contaminants reduces odours & prevents the water from going yellow. Its use will keep the water looking like new as well as improving its quality for your fish. Carbon should be replaced every 4 to 6 weeks as over time it becomes saturated 5. Tetra Tec FF Filter Floss reliably removes very fine particles of waste thus helping to give the water a final ¿polish¿. This coupled with the carbon ensures the aquarium remains crystal clear. Tetra Tec FF Filter Floss should be replaced when it becomes dirty.
