Aquaroche FAQ | Ceramic Aquarium Rocks, Reef Scaping, Cycling & Tank Setup Guide

Product Safety & Material

What are Aquaroche ceramic rocks made of?
Aquaroche rocks are made from natural, high-temperature fired ceramic clay. They are chemically inert, non-toxic, and safe for all freshwater and marine aquariums.
Are Aquaroche products safe for reef tanks and sensitive corals?
Yes. Aquaroche ceramic structures are completely reef-safe. They do not release any harmful substances and provide a stable, porous surface for beneficial bacteria and coral attachment.
Do Aquaroche rocks affect pH, KH, or water chemistry?
No. The ceramic material is neutral and does not alter aquarium water parameters, making it suitable for both freshwater and marine systems.
Are Aquaroche rocks porous?
Yes. Each piece is designed with micro- and macro-porosity to encourage biological filtration and provide shelter for microorganisms and small aquatic life.
How long do ceramic rocks last in an aquarium?
Aquaroche rocks are extremely durable and do not decompose, dissolve, or break down over time. They can be used indefinitely.

Do I need to rinse Aquaroche rocks before placing them in the tank?
A quick rinse with clean water is recommended to remove dust from the manufacturing process. No chemicals or treatments are necessary.
How should I arrange Aquaroche rocks for stability?
Use the natural shapes, flat bases, arches, pillars, and plates to create a stable structure. Ensure weight is evenly distributed and avoid placing heavy items on unstable points.
Can I drill, cut, or modify Aquaroche rocks?
Yes. Ceramic can be drilled or cut with appropriate tools. Proceed slowly and carefully to avoid cracking.
Are Aquaroche rocks compatible with live rock?
Yes. Many aquarists combine Aquaroche with natural live rock to seed beneficial bacteria while creating a stable, customizable aquascape.
Do Aquaroche rocks float?
No. They are dense and naturally sink immediately.

Do Aquaroche ceramic rocks require cycling?
The rocks themselves do not need cycling, but your aquarium system must be cycled before adding livestock.
How long does cycling take with Aquaroche rocks?
Similar to traditional rock setups—typically 2–6 weeks depending on your biological starter media, tank size, and filtration.
How can I speed up the cycling process?
You may use:
- bottled beneficial bacteria
- live rock or live sand
- bacterial starters from an established aquarium
- proper water flow and oxygenation
Will Aquaroche rocks host beneficial bacteria?
Yes. Their porous structure is designed to encourage the growth of nitrifying and denitrifying bacteria, supporting healthy biological filtration.
Do Aquaroche rocks reduce nitrates or improve filtration?
They provide additional surface area for bacterial colonization, which supports the nitrogen cycle and enhances biological stability.

Are Aquaroche rocks suitable for SPS, LPS, and soft corals?
Yes. The surface texture allows easy coral frag mounting and long-term stability for all coral types.
What is the Acroporock system used for?
Acroporock is designed specifically for coral frags. It provides stable bases and elevated structures ideal for SPS and LPS propagation.
Can I glue coral frags onto Aquaroche rocks?
Yes. Reef glue or epoxy adheres well to the ceramic surface.
Do Aquaroche structures support heavy overhangs or tall reef aquascapes?
Yes. Arches, pillars, and Eco Reef Plates are engineered for modular stacking and stable load-bearing designs.
Do Aquaroche rocks encourage coralline algae growth?
Yes. Their surface allows coralline algae to colonize naturally over time, giving the rocks a natural reef-like appearance.

Are Aquaroche rocks safe for planted tanks?
Yes. They do not alter water chemistry and can be used in planted aquariums and nature-style layouts.
Are they appropriate for cichlid tanks?
Absolutely. Cichlids benefit from the caves, hiding spaces, and territorial boundaries the rocks provide.
Can I use Aquaroche rocks in nano tanks?
Yes. Smaller pieces and nano-specific models are available for compact aquariums.
Will ceramic rocks grow algae?
Like any aquarium hardscape, algae may naturally grow depending on nutrients and lighting. It is normal and can be controlled with routine maintenance.

How should I clean Aquaroche rocks during maintenance?
Use clean tank water or RO water. Avoid soaps or chemicals. For algae, use a soft brush.
Can I bleach or acid-wash Aquaroche rocks?
Avoid strong chemicals unless absolutely necessary. If used, rinse thoroughly and soak in dechlorinated water before reuse.
Are Aquaroche rocks fragile?
They are highly durable, but like all ceramic products, they can break if dropped or struck hard.
Do the rocks come pre-seeded with bacteria?
No. They are clean ceramic structures. Beneficial bacteria will develop naturally once placed in a cycled tank.
Do you offer custom aquascaping structures?
Yes. Large-scale custom designs are available for public aquariums, coral farms, and specialty installations.
Where are Aquaroche products manufactured?
All Aquaroche products are proudly made in France.
