Full details
Marina Decorative Aquarium Gravel is an ideal choice for aquarists looking to enhance the visual appeal of their aquatic environment without compromising water quality.

FAQs
Is this gravel safe for bottom-dwelling fish like corydoras?
Yes, the gravel is inert and non-toxic, but ensure the grain size is appropriate for your specific species to prevent injury to their barbels.
Can I use this in a saltwater tank?
Yes, the epoxy coating is designed to be stable and safe for both freshwater and saltwater chemical environments.
Do I need to wash the gravel before use?
Yes, even though it is marketed as dust-free, a quick rinse in a bucket is standard practice to ensure the clearest water possible from day one.
How many bags do I need for a 20-gallon tank?
A 20-gallon tank typically requires approximately 4-6kg of gravel for a standard base layer, so you would likely need 2-3 bags.
Will this change my water pH?
No, the gravel is completely inert and will not interact with your water chemistry.
Troubleshooting
Water appears cloudy after initial setup
This is likely residual dust; perform a 50% water change and ensure the filtration system is running to clear the remaining fine particles.
Algae growth on gravel surface
Reduce light exposure duration and ensure you are vacuuming the gravel regularly to remove excess nutrients that fuel algae.

Setup, Compatibility & Care
Before adding to your aquarium, rinse the gravel thoroughly in a bucket until the water runs clear, as transport may cause minor abrasion. Gently spread the gravel across the bottom of the tank to the desired depth, usually 2-3cm for aesthetic purposes or deeper if you intend to use it with an under-gravel filter. It is compatible with all standard aquarium heaters and internal filters. For ongoing care, use a gravel siphon during routine water changes to remove trapped waste particles from the crevices, ensuring the surface remains clear for oxygen flow and bacterial health.
