Aquaforest AF Nano Rock 3.5 kg — Porous Rock for Marine Nano Aquariums 8 lb

Aquaforest AF Nano Rock 3.5 kg — porous rock for nano marine aquariums 8 lb

The AF Nano Rock 3.5 kg is the nano-reef-sized version of Aquaforest's synthetic rock lineup. Hand-crafted from natural ingredients, piece size and shape tuned for 20-100 L aquariums where big rock chunks would be out of scale. High-porosity for max biological exchange surface on a balanced nano reef.

The 3.5 kg (~8 lb) bag typically covers a full aquascape on a 30-60 L nano tank, or tops up an existing aquascape on a 100-150 L tank.

Nano Rock features

• Nano-scale format — pieces sized for small volumes.
• High porosity — maximum bacterial exchange surface for nano biology.
• Natural composition — premium selected ingredients, visually close to live rock.
• Contaminant and parasite-free — total safety for nano fauna.
• Cuttable and joinable — Stone Fix compatible for custom aquascape.

Nano-reef use

• Rinse with prepared saltwater before installing.
• Assemble the aquascape before final tank fill.
• Create overhangs, arches, or towers using Stone Fix.
• Complete cycling with Bio S and Bio Sable for fast biological startup.

Frequently asked questions

How much Nano Rock for a 40 L tank?

About 2-3 kg of Nano Rock cover a 40 L (10 US-gal) tank aquascape, a bit less than a 3.5 kg bag. The 1-1.5 lb per gallon rule still applies on nano — smaller pieces allow more precise placement.

Is Nano Rock different from AF Rock 18 kg?

Composition is identical. Only piece size changes — Nano Rock ships smaller chunks better suited to a nano-reef aquascape. On a 100 L in-between tank, you can mix both formats.

Does full cycling matter before adding corals?

Yes — since Nano Rock ships dry, it needs a full biological cycle in the tank before adding sensitive livestock. Plan 2-4 weeks with Bio S and Bio Sable to speed up, versus 4-8 weeks without bacterial add-ins.
