Where do you put crushed coral in a fish tank?
Coral skeletons that make up crushed coral consist of calcium carbonate, which helps increase your aquarium’s pH level up to 7.6 without the use of any chemicals.

Registered. Your using commercial substrate with gravel it looks like. You can do it, but not sure a gravel “cap” will not end up mixed in the end. Prob better to just mix it, but might not look the best!
