Kruger Meier Ivory Ash Lava 8-16 mm - Aquarium gravel 2kg

This substrate looks unusual, but it works exceptionally well. Ivory Ash Lava is a porous volcanic rock in a subtle, light shade. Thanks to its structure full of micropores, it supports the growth of nitrifying bacteria – those responsible for clean, healthy water in your aquarium.

You can use it as a bottom layer substrate, create an impressive arrangement with it, or pour it directly into the filter chamber. It works long-term, does not affect water parameters, does not crumble or stain. Plus, it looks light and natural – especially in modern or bright arrangements.

It’s more than just a stone – it’s an active ally in maintaining balance.

Why is it worth having?
Porous lava – ideal for colonization by filter bacteria
Bright, unique color – beautifully illuminates the bottom of the tank
Can be used as a substrate or filter media
Does not affect water parameters – safe for all aquarium inhabitants
Natural environmental stabilization – reduces the risk of algae and parameter spikes
Durable, lightweight, and does not break down over time

Tip:
Rinse before use – it may contain dust from transport. Then pour into the filter, use as a bottom layer in the tank, or showcase it in an arrangement. It works, cleans, and… just looks great.
