Product Overview

Aquariums & Ponds

The aquarium & pond filter & bio media division – ‘Koi-PAK’ filter & biological carrying media.

‘Koi-PAK’ media is manufactured in polypropylene material with a density of 0.92 which gives the advantage for the media to remain buoyant which allows the bottom of the filter or reactor tank to remain free from media and help to prevent blockage.

If you require a ‘Koi-PAK’ media which will sink and remain at the bottom we can mold any sizes given in a polypropylene to give a density of 1.05. If this density is required this must be stated on your order.

‘Koi-PAK’ is based on the well proven Pall Ring design with high surface area and openings in the side to aid liquid flow and reduce blocking and fouling.

‘Koi-PAK’ is non toxic, non taint and highly resistant to degradation and oxidation.

‘Koi-PAK’ is easy to clean and will give many years of service.

Easy to order either by phone or email. Most credit cards are accepted. If you email your order please advise your phone number so we may call you to confirm your order and method of payment.
