Hugo Kamishi Polario Gravel 8-12mm
The Polario gravel is a mixture of multi-coloured natural stone. Once wet, these stones display the most incredible colours.
We always recommend rinsing any substrates before placing them into your aquarium.
Gravel in any aquarium enhances the look and also serves important functions.
The most important function gravel provides is to offer a home for beneficial bacteria. These bacterial colonies are essential to break down waste produced by fish, leftover food, and plant debris in the aquarium. If bacteria do not have a suitable gravel bed to inhabit, they may find alternative areas, but may not establish in sufficient numbers to maintain a safe environment for your fish.
