Pettex Aquatic Roman Gravel Natural Alpine

Choosing a named colour of gravel rather than a mixed bag is really about knowing what you'll see through the glass before the box is even opened, and a plain white gives an aquascape a clean backdrop that coloured or patterned gravel doesn't.

This is Pettex's Roman Gravel range in Alpine White: a natural aggregate rather than a dyed or resin-coated one, so it carries the colour and size variation you get with any natural material. It works across coldwater, tropical and saltwater set-ups, and its increased surface area also makes it usable as a planting medium.

• Natural aquarium gravel, colour: Alpine White
• Suitable for coldwater, tropical and saltwater aquariums
• Also functions as a planting medium
• Helps maintain pH stability in the tank
• Colour and grain size can vary piece to piece, being a natural product
• Sold by Pettex, in more than one pack option

On consistency. Because it's a natural gravel rather than a manufactured, uniform one, expect some variation in shade and grain size within the bag — that's the trade-off for it not being dyed. This page also covers more than one pack size; check the option you select for the exact quantity you'll receive.

Who it's for: fishkeepers setting up a coldwater, tropical or saltwater tank who want a plain white natural gravel rather than a coloured or mixed one.
