Dry Ocean Reef Rock 9-13cm

These rocks are not inert and will release minerals into the water. They are not suitable for soft water shrimp setups and should only be used in tanks with hard water shrimp (Cherry, Amano etc.) or marine tanks. Regular water changes as part of maintenance, advisable. These are sometimes used in certain sulawesi shrimp setups.

Please note: the price is per kg

Weight and size always varies by type of rock. We will try to mix and match your chosen weight as closely as possible, but this can't always be guaranteed! If you have a preference in number of rocks or size, please leave a note during checkout and we will try to accommodate where possible. Since this is a natural product individual rocks will vary. You are welcome to pick out your own pieces by visiting our shop in Mansfield.


Always rinse and clean rocks before adding them!

Michael ★★★★★

The mineral release is exactly what my hard water cichlid tank needed; each piece has great texture and crevices for hiding spots. Rinsed them well and they didn't cloud the water at all.

Ruby ★★★★★

Picked up a kilo of these for my African cichlid tank and the 9-12cm pieces are perfect for building stable caves. The rock structure is very porous, which my fish love hiding in, and after a few weeks the minerals have helped keep my pH steady where I want it.

Samuel ★★★★★

These rocks look great in my hard water cichlid tank and the 9-12cm size is perfect for building stable caves. They definitely release minerals like described, so my water parameters are exactly where they need to be.
