Sera Filter Wool – 250g

For mechanical prefiltration of fine dirt particles

Sera filter wool for the mechanical prefiltration 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. 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, sera filter wool makes it easier to remove the bound substances.

Choosing and using it

The 100g pack suits small filters, while the 250g pack is better value for large canister filters or several tanks. Cut a layer to fit and place it before the biological media, so fine dirt is trapped before it can clog them. Rinse it in old tank water when flow slows, and replace it once it stays compacted or discoloured after rinsing. A fresh layer also helps polish cloudy water quickly after you disturb the gravel.
