Maintaining optimal water quality is fundamental to successful aquaculture, hydroponics, and ornamental water features. Aogochem's Calcium Carbonate (CaCO₃) Balls are a precisely engineered, mineral-based solution designed to naturally and safely improve water parameters. These high-purity calcium carbonate spheres function as a slow-dissolving buffer, gradually releasing calcium (Ca²⁺) and carbonate (CO₃²⁻) ions into the water. This controlled dissolution provides a dual benefit: it neutralizes acidity to raise and stabilize pH levels and increases water hardness (KH and GH), which is crucial for the health of fish, shrimp, and beneficial bacteria. Unlike quick-dissolving powders or unstable chemical additives, our CaCO₃ balls offer a sustained, long-term release, preventing harmful pH swings and providing a constant source of essential minerals. They also serve as a beneficial biological filtration substrate. Aogochem offers standard sizes for direct application and full customization, allowing for tailored dissolution rates and shapes to meet the specific demands of your system—from large-scale shrimp farms and fish hatcheries to recirculating aquaculture systems (RAS) and hobbyist ponds.
Our Calcium Carbonate Balls are manufactured from high-purity limestone or precipitated calcium carbonate to ensure consistent performance and minimal impurities.
| Property | Specification | Significance / Benefit |
|---|---|---|
| Chemical Composition | Primarily Calcium Carbonate (CaCO₃), > 95% purity. | Provides the source of buffering ions (Ca²⁺ and CO₃²⁻) for water conditioning. |
| Available Sizes | 2-4 mm, 3-5 mm, 4-6 mm (Standard). Other sizes available upon request. | Different sizes suit various flow rates and application methods (e.g., in bags, fluidized beds, or scattered). |
| Crushing Strength | > 20 N per ball. | High mechanical integrity ensures minimal breakdown into fines during handling and use, maintaining water clarity. |
| Bulk Density | > 1.0 g/cm³ (Typically ~1.2 - 1.4 g/cm³). | Indicates a solid, non-hollow structure for consistent dissolution and easy calculation for dosing. |
| Solubility | Slowly soluble in weak acidic water. Dissolution rate depends on water pH, temperature, and flow. | Provides a long-lasting, controlled release of minerals without causing rapid pH spikes. Ideal for continuous conditioning. |
| Function | pH Buffer & Hardness Increaser. Neutralizes acids (H⁺) via reaction: CaCO₃ + 2H⁺ → Ca²⁺ + CO₂ + H₂O. | Stabilizes pH in the optimal range (e.g., 7.0-8.5 for most aquaculture), prevents "pH crash," and supplies essential calcium. |
| Additional Benefit | Provides surface area for beneficial nitrifying bacteria colonization. | Supports the biological filtration cycle alongside its chemical conditioning role. |
1. Aquaculture & Mariculture:
Use: Added directly to ponds, placed in mesh bags in inlet water streams, or used in fluidized chambers in Recirculating Aquaculture Systems (RAS).
Benefit: Stabilizes pH in systems prone to acidification from feed waste and respiration. Increases alkalinity (KH), which protects against sudden pH drops and is vital for shrimp molting and shell development. Provides a supplemental source of calcium, crucial for skeletal and exoskeleton growth.
2. Ornamental Ponds & Aquariums:
Use: Placed in filter bags within canister or sump filters, or scattered in the filter chamber of pond systems.
Benefit: Safely raises and maintains pH and hardness for fish and plants that prefer alkaline, hard water conditions (e.g., African cichlids, livebearers). Creates a more stable environment than liquid additives.
3. Hydroponics & Aquaponics:
Use: Incorporated into grow bed media or placed in a separate reactor vessel through which nutrient solution circulates.
Benefit: Counteracts the natural acidification caused by plant nutrient uptake and nitrification. Provides calcium, a key plant nutrient, in a readily available form.
4. General Water Treatment:
Use: For gently adjusting the pH and hardness of source water in various agricultural or light industrial applications where a mild, sustained correction is needed.
Custom Shapes & Sizes: We can produce CaCO₃ media in various forms—pellets, granules, or custom shapes—to fit specific reactor designs or application equipment.
Tailored Dissolution Rates: By adjusting the raw material density, particle size distribution, and manufacturing process, we can modify the dissolution profile to match your system's demand.
Composite Formulations: Potential for creating blended media with other functional minerals or compounds for specialized water conditioning needs.
Dosage: Start with a recommended dosage based on system volume and initial water hardness (e.g., 0.5-2 kg per cubic meter of water). Monitor pH and KH regularly to adjust the amount.
Placement: For best results, place media where there is consistent water flow to ensure even dissolution and distribution of ions. Avoid dead zones.
Replacement: The media will slowly dissolve over time. Replenish when the bed volume noticeably decreases or when target water hardness levels begin to fall.
Compatibility: Safe for use with fish, plants, and beneficial bacteria. It is a natural mineral product.
