Great looking gravel supplied in strong polythene bag and packed in box. as recommended, it needed only minimal rinsing - just to remove a very small quantity of dust.

Fantastic fine gravel that has very little dust and muck in it. It still needs a wash and is best to use a plastic sieve to ensure that the really tiny pieces of gravel are filtered out. Fish and Shrimp love it and plants can be buried with no damage to the roots.

hello I have purchased this gravel for my nature aquarium but been told that it is not good for cory's as when the dig around the gravel it can cause cuts to their barbels. thanks andy


Well, some hobbyists seem OK with it and corys aren't bothered. Just keep an eye on them and see how they get on :)

Is thus gravel coated


Hi, will this gravel impact PH?

Perhaps a tiny bit but nothing of any concern
