Sera Filter Wool

Sera Filter Wool is for mechanical pre-filtration of fine dirt particles. The mechanical pre-filtration consists of stable fibers that retain finer dirt particles for a longer time without sticking or collapsing. Sera filter wool can be washed out several times. It is suitable for all filters. We recommended sera siporax Professional for the biological filtration. Sera siporax professional is open pored and three dimensional – for lasting pollutant breakdown. Sera filter media must be rinsed under warm water before using it for the first time. Tip: When used in combination with sera phosvec?clear and sera pond crystal, sera filter wool makes it easier to remove the bound substances. Weight: 100 grams
