Even after washing, lava rock will produce some powder just from rubbing, so please open the package outdoors or on top of newspaper or a trash bag.

Lava rock is favored by microorganisms and bacteria, which break down harmful substances in the aquarium water, purifying and stabilizing it.

Recommended as it lasts longer than soil or akadama soil.

For reuse, it is recommended to wash with aquarium water, as tap water or boiling will reduce or kill the bacteria.

Many comments received indicate that it is often used as filter media for biotope tanks.

【Treatment Method】
Washed, boiled for 1 hour, de-colored for 1 week, sun-dried.

【Ships within 1-2 days】
