## Overview

Suitable for both fresh and saltwater tanks, this dust-free gravel combines durability with vibrant colour to create a stunning underwater landscape.

## Description

From the manufacturer Marina Decorative Aquarium Create a colourful aquascape in your aquarium with Marina Decorative Gravel. The gravel is epoxy-coated, which makes the gravel inert and prevents any adverse effects on water chemistry. Research shows that epoxy-coated gravel provides an optimum surface for the colonization of beneficial bacteria, which in turn provide biological filtration for clear and healthy water. The gravel is dust free and is available in a wide variety of colours. For fresh water and saltwater aquariums.

Review: Losing colour after one year. - After a year the layer with color is peeling off and the gravel is becoming white on some parts. A sign of high-quality epoxy I suspect.
Review: TOXIC!!!!!! - We put our 2 goldfish in a new tank with this gravel and within hours they had died! We got another which started dying too, so my husband got it out and put it back in its old tank (no gravel) and it came back round. He said the gravel smelt like paint so I read some reviews on here which also claim that the gravel killed their goldfish...he threw the gravel out, cleaned the tank and put the goldfish back in and they've been fine since! So PLEASE DO NOT BUY THIS PRODUCT !!!! It is toxic and poisons fish!!!!!
