This live sand is intended for marine aquarists setting up a new saltwater tank or stabilising an established reef system. Its main function is to introduce a bacterial biofilm into the substrate, which supports the biological processes a tank needs before it can handle its nitrogen load.
Why it matters
- The sand is natural aragonite with its biofilm kept alive, not artificially inoculated, according to the manufacturer.
- Bacteria are preserved using the patented QX-23® seawater-enriching solution, which the manufacturer states keeps them in their natural state.
- The manufacturer states the sand supports immediate nitrification and helps reduce ammonia, nitrite and nitrate, which are the nitrogen compounds that build up in marine water.
- Stated effects also include limiting algae growth and biofouling and stabilising pH, with no additional preparations required to maintain biological balance.

What it works with

The product page does not specify tank volumes, so the quantity needed for a given aquarium should be checked against the tank's dimensions and planned depth.
