Volcanic natural substrate for aquascaping

  • Volcanic rock substrate as stable foundation for rock and root wood constructions: dedicated substrate for aquascaping aquariums
  • Basis substrate for natural aquariums: porous volcanic rock ensures water circulation at the bottom. Supplies plant roots with organic plant nutrients
  • Vigorous plant growth: ideal oxygen supply and circulation through open-pored structure. Long-term supply with nutrients and minerals
  • Safe foundation, no slipping: volcanic rock becomes firmly interlocked. Ideally suited for a firm foundation

Product information

Underwater gardener
Aquascaping is the term used for designing aquarium landscapes. This is where plant compositions, reproductions of landscapes above water or natural biotopes are created. An aquascaping aquarium contains no or few fish and invertebrates. This way the nutrient supply for plants is reduced and their growth is limited. Nitrogens, phosphorus and other minerals become scarce substances and need controlled and exact re-dosing. For healthy growth in their beautiful underwater landscape the plants need light, CO2 and the right nutrients.
Volcanic rock
The highly porous volcanic rock fulfils important functions in an aquascaping aquarium: Firstly it forms a stable foundation for further rock constructions and/or root wood, which would otherwise slip downwards through the soil. Secondly many beneficial bacteria settle inside the porous structure. The porousness of the rock structure also enables the nutrient to penetrate it and it thus supplies numerous minerals enabling the plants to take root and grow well inside it.
The calculation formula for the right amount of substrate is: length (cm) x width (cm) x height (cm): 1000 = litres JBL ProScape VolcanoMineral

May I use an undergravel heating cable for this substrate?

Yes, this combination with an undergravel heating cable is no problem.

Blog (opinions & experiences)

Why is there the JBL PROSCAPE programme in addition to the JBL PROFLORA?

There is a lot of feeding in a community aquarium and this provides a certain amount of nitrogen and phosphates. In a plant-dominated aquarium these nutrients are in short supply and need to be added separately.

This is one of my favourite products from JBL. I always use Volcano mineral below my soil for a couple of reasons. First of all, this product promote the substrate circulation and decreases the anaerobic areas, and helps a lot with algae problems. In addition, you can use it to increase the depth at the back of your tank and built a high and stable structure.


Daves scapes

Volcano mineral is great to build up a stable foundation for rockwork or for building up high areas in the background of an aquascape. Also because of its porous structure it helps promote substrate circulation which in turn really helps the bacteria colonies which in turn help to provide a healthy aquarium system. I do and would definitely recommend to anyone

ShrimpPuddle - German

Sehr gutes Lavagranulat was nicht für Aquascapes geeignet ist, sondern auch sehr gut für Bodenfilter und UGF Boxen. Wichtig bei der Verwendung als Filtermaterial, man sollte es vorher einige male gut ausspülen.

C. Kischnick - German

Die beste erste Schicht in unseren Aquarien! Super durchflutung der Wurzeln und es garantiert einen optimalen Aufstieg nach hinten. Ganz klare Empfehlung!

S. Kübler - German

Absolutes "must have" für jeden Aquascaper! Perfekt für den Aufbau des Bodengrunds. Sorgt für eine gute Durchlüftung des Bodens und bietet gleichzeitig noch Besiedlungsfläche für wichtige Bakterien 👍

G.E.P.P. - French

Bon support bactérien je vais le recouvrir de manado dark

freshwaterscapes - Dutch

One of the products from JBL I always use below my soil. The porous matieral promotes the water circulation through the soil, and promotes bacterial life. A better bacterial colony promotes a healthier aquarium. On top of that it's an easy product to increase the height of your aquascape in a very stable way. I used this product with volcano mineral and my plants are very healthy.

marcs.jungle - German

Das beste Zeug auf Erden ☺️ meistens ausverkauft, da es unverzichtbar zum Aufbau von Hardscape ist

Aquawelten - German

Um den Boden zu "lüften", habe ich mich für mein Iwagumi für einen 1. Bodengrund bestehend aus dem Volcano Mineral entschieden. mit 2. Schicht aus Soil eine perfekte Basis für ein gutes Scape!

betta.marcel - German

Must have, wenn ein Aquascape länger als ein paar Monate stehen soll. Denn Soil verdichtet sich. Die Folge davon: Cyanos wegen der schlechten Zirkulation. Dem wirkt Volcano Mineral durch Zwischenräume und seine feste Struktur entgegen. Weiterhin ist der Lavabruch eine klasse Ergänzung zum Filter, da die poröse Oberfläche viel Siedlungsfläche für nützliche Bakterien bietet.

ProTipp: Volcano Mineral in einem Filternetz (nicht zu feinmaschig) nutzen. So vermischt sich dieses nicht mit dem Soil.

G.E.P.P. - French

Taille et ph idéal pour l'aquariophilie

Einfach klasse ! Bietet eine super Grundlage / Ausgleichsschicht für Hardscape jeglicher Art und lässt das Wasser gut zirkulieren.

Ich nutze es als Untergrund für eine weitere Soil-Schicht !

M. Karaahmetoglu - German

Ich verwende seit vielen Jahren in jeder Aquarieneinrichtung das JBL-Volcano-Mineral-Produkt, das die erste Schicht ist, die bei der Aquarieneinrichtung auf dem Boden verwendet wird. Das größte Merkmal, das ich beobachtet habe, ist, dass es sauber und gewaschen aus der Verpackung kommt. Wenn Sie es Ihrem Tank hinzufügen, wartet keine dichte Staubschicht auf Sie. Ich kann auch sagen, dass es dank seiner reichen mineralischen und porösen Struktur ein großartiges Zuhause für nützliche Bakterien ist.

Świetny produkt który zapobiega tak zwanym strefom beztlenowym w akwarium. Rośliny świetnie się ukorzeniają w takim podłożu wzbogaconym o JBL PROSCAPE VOLCANO MINERAL.

Aqua4Scape - German

Nehme ich bei all meinen Bedenken. Damit lassen sich schöne Strukturen im Becken aufschütten und die Poren bieten super Halt für Wurzeln und Bakterien.

Der_Egger - German

Ohne geht´s nicht. Eine bessere Grundlage für gesunden Boden im Aquarium kann man nicht haben.

Seid ich das Vulcano als erste Schicht im Boden habe, hatte ich noch nie Faulstellen o.ä. in meinem Aquariumboden.

Zusätzlich bietet das offenporige Vulkangestein einen idealen Nährboden für nützliche Bakterien.

Außerdem lässt mit Vulcano eine tolle Tiefenwirkung in den Aquarien / Aquascapes erstellen. Rundum ein tolles Produkt.

exotic_hive - German

Schafft eine optimale zurkulation unter dem Bodengrund. Ob Soil oder Kies, man merkt ihn absolut!

Aquaklausi - German

Kein Aquarium oder Aquascape ohne Vulkangestein als 1. Bodenschicht.

Ich habe jetzt in 2 Jahren 6 Becken mit dem Volcano eingerichtet. Ich habe nie Probleme mit dem Boden gehabt wie z.B. Faulstellen oder Faulgasbildung.

Durch die Poröse Oberfläche siedeln sich die wichtigen Bakterien fürs Aquarium an dem Vulkangestein an. Somit ist der Bodengrund ein großer zusätzlicher Filter. Ein Becken läuft so viel stabiler und auch für die Pflanzen ist es super und sich mit den Wurzeln fest zu verankern.

Mein Tipp. Ein Aquarium sieht deutlich besser aus wenn der Bodengrund nach hinten ansteigt. Um den Bodengrund höher aufzubauen eignet sich das Volcano Mineral perfekt!

Aqua_M.e.n - German

Einfach ein Muss, wenn man an Höhe in seinem Aquarium oder Aquascape gewinnen möchte. Auch Top als Ansiedlung für Bakterien 😊👌
