Retention Wool

Supplied in rolls 50m x 27

A very useful filtration media for those filters that are using a 'down flow' system in their first settlement chamber - the incoming water from the pond should be allowed to drop over the top of this retention wool ... you will be amazed how much filth it will stop entering the biological side of your filters .. and of course this also stops it from re-entering your pond ...
