Coral finger ECOPACK 4Kg

Coral finger is a natural substrate for limestone reactors.

This 8-12mm grit coral sand is not subject to CITES, is 100% natural and collected from pollution-free areas.


The natural origin of this substrate allows a completely safe supply of calcium and trace elements. A dissolution from pH 7.1 makes this substrate particularly interesting for limiting the amount of CO2 in the limestone reactor.

We recommend soaking the finger coral in reverse osmosis water for 48 hours and then rinsing it before use to facilitate degassing in the reactor.
