Aquaforest AF Rock 1 lb — Porous Reef Rock Sold by the Pound

Aquaforest AF Rock 1 lb — porous reef aquarium rock sold by the pound

The AF Rock 1 lb ships Aquaforest's synthetic reef rock by the pound, for reefers building their aquascape in small progressive additions or completing an existing setup. Hand-crafted rock from natural ingredients, composition similar to live rock but without parasite risk, unwanted algae, or bad hitchhikers.

1 lb (0.45 kg) format ideal to top up an aquascape with small pieces, add coral mounting points, or test AF Rock before larger-volume commitment.

What sets AF Rock apart

• High-density porosity — maximum biological exchange surface for nitrifying bacteria.
• Parasite-free — no flatworm, pest snail, or nuisance algae risk.
• Lightweight — lighter than classic synthetic ceramic rocks.
• Natural calcium carbonate — contributes to tank pH and alkalinity stabilization.
• Cuttable and joinable — handy for complex aquascape built up piece by piece.

Use

• Rinse in saltwater before installing to clear dust.
• Place directly in the tank or combine with other rocks.
• Progressive bacterial colonization — accelerate with Bio S and Life Bio Fil.
• Ideal to create overhangs, caves, and fauna refuges.

Frequently asked questions

How many pounds for a 30 US-gal aquascape?

The classic rule is 1-1.5 lb of rock per gallon of water, so 30-45 lb for a 30 US-gal tank. Buying by the pound lets you precisely tune the amount to the desired aquascape shape (thin columns vs solid block).

Does AF Rock need pre-cycling?

AF Rock ships dry and not pre-seeded — it needs classic biological cycling in the tank. Plan 3-4 weeks for full bacterial colonization, faster with liquid Bio S or Bio Sable.

Can I mix AF Rock with rocks from other brands?

Yes — AF Rock is visually and chemically compatible with most synthetic reef rocks on the market. The natural calcium carbonate composition blends with classic live and ceramic rocks.
