Filter Media

 

Here are some different types of Filter Media

1 - Biohome Standard

A compact sintered glass media suitable for overhead filters, trickle filters, sumps, external and internal filters.

2 - Biohome Plus

As above but with additives to ensure much faster colonisation by bacteria.

3 - Biohome Ultra

A larger version of Biohome standard with rougher feel. Possibly the best media available. Suitable for trickle towers, sumps, larger external filters, overhead filters and multi chamber koi filters.

4 - Biomotion

A rounded sintered glass media with neutral buoyancy. Suitable for moving bed filters, overhead filters, trickle filters, sumps, external filters and internal filters. Has montmonrolite clay coating to condition water.

5 - Ceramic Rings / Noodles

Ceramic media with variable surface area depending on quality. Suitable for external filters, overhead filters, internal filters, trickle filters and sumps.

6 - Bio Sponge Ball

Plastic media with added internal sponge to trap solids and support extra bacteria. Suitable for filters with a fast flow through rate e.g. Koi filters, Shower filters (before ceramic media) and large external filters.

7 - Hel-x

Plastic filter media which is an evolution of K1. Has approx 40% more surface area than K1 per litre. Supports very hardy bacteria which rapidly consume ammonia and nitrite. Suitable for moving bed filters and high demand applications (koi or large aquariums).

8 - K1

Most widely used plastic moving bed filter media. Has less surface area than Hel-x but is smaller so can be used in tiny filters. Supports vigorous bacteria as above. Suitable for moving bed filters.
