Eheim Substrat Pro is a biological media. 

This type of filtration is the purification of the aquarium water by using living organisms, such as denitrifying bacteria. These desirable bacteria will attach themselves to all hard surfaces within the aquarium system. They use the toxins as a food, converting harmful toxins such as ammonia and nitrite into less harmful nitrate. After prolonged use, mechanical and chemical filter media will act in a biological manner. They provide some surface area for bacterial colonization but this is actually very limited. 

In order to provide the greatest amount of surface area for bacteria colonies, filter media such as Eheim Substrat Pro should be used.

Bulk items requiring Pallet delivery are different...

Certain items, such as glass aquariums & large cabinets, require special handling and must be sent out on a pallet, this is at a cost starting from £19.99 on some pallet deliveries depending on location. We don't offer free pallet delivery unfortunately (unless stated) due to the delicate nature of the glass aquariums and insurance required to transport.

We will contact any pallet delivery purchase before dispatch to arrange a suitable delivery date for you to receive the goods. We will not dispatch a aquarium pallet delivery until we have booked a delivery date with you the customer.

Note that the pallet delivery service is a drop at kerb only service, the drivers are not insured to handle goods into homes and you are required to dispose of the pallet.
