Simply The Best!

Calico's live rock

Indonesian rock is very similar to the rock imported from Fiji and Tonga, but it tends to be more porous, making it great value for money. Due to licensing, it is much harder to import than other types of rock at the moment, but it is still the best!

We only ship our most colourful pieces and always supply a variety of shapes and sizes, allowing you to create the perfect aquascape.


We are offering our premium rock at £9.00 per kilo or £8.50 per kilo for 20 kilos or more.

Free delivery on 20 kilos or more!


What is so special about live rock?

The quality of all living rock is determined by age and porosity. The outer light baring area is inhabited by photophilous organisms and macro micro algae, where as the unlit outer area supports photophobic life such as sponge, tunicates and crustaceans. Towards the core, numerous bacterial colonies thrive, whilst the core itself is home to nitrate reducing anaerobic bacteria that flourish in the dark, low oxygen environment.

This complex array of organisms provide living rock with unique filtration capabilities and when used in the correct quantity (half a kilo per gallon minimum) will delicately balance all types of marine ecosystem, providing the finest filtration money can buy.

When living rock arrives at our premises it is unpacked, cleaned and placed in huge salt water vats where a surface area die off process takes place. The rock completes the nitrogen cycle, replenishing the outer layers destroyed by transportation. This curing process can take up to five weeks.

Due to the impractically high cost of transporting living rock immersed in water, it is kept moist in wax boxes. This has proved to be a very successful way of maintaining premium quality living rock, the perfect natural system for a living reef.

Remember, you need half a kilo per gallon as a minimum.
