Oyster shell chips (in fine grind it is shell powder) serves as natural water conditioner, as well as natural filter media. The main effects of Oyster shell chips in saltwater aquarium are: 1) Acting as a buffer to help stabilize pH and Alkalinity, 2) Supplement calcium, carbonate minerals and trace elements, 3) Provide biological filtration surface.
How it works:
1) Oyster shells are primarily composed of calcium carbonate (CaCO₃). In the slightly acidic environment of aquarium water, calcium carbonate dissolves very slowly. This dissolution process releases carbonate (CO₃²⁻) and bicarbonate (HCO₃⁻) ions into the water, which are the very components that make up "Carbonate Hardness" (KH) or Alkalinity. By slowly dissolving, oyster shell chips provide a steady, passive source of this buffering capacity, helping to prevent pH crashes, especially in smaller or less stable systems.
2) As the shells dissolve, they also release calcium (Ca²⁺) ions into the water. Calcium is an essential element for all calcifying organisms, including corals, coralline algae, clams, and snails. They can also leach a variety of trace elements and minerals found in seawater, such as strontium and magnesium, albeit in uncontrolled amounts.
3) The porous structure of oyster shell chips provides a massive surface area for beneficial nitrifying and denitrifying bacteria to colonize. When used in a filter media bag (e.g., in a sump or canister filter), they can act as an additional biological filter.
Usage: Oyster shell chips are best suited for specific, low-demand scenarios, as low-maintenance beginner tank "set-and-forget" method. Or the contrary, in advanced use in calcium reactors, that is the most effective use in a reef tank. In a calcium reactor, oyster shell chips are placed in a chamber and exposed to water with a low pH (via injected CO₂). This forces rapid dissolution, creating a calcium and alkalinity-rich effluent that is then dripped into the tank. In this controlled application, they are highly effective.
Cautions: Oyster shells are a natural, biological product. Organisms can incorporate phosphates from their living environment into their shells, and then bring those phosphates with those shells to aquarium water. It's recommended to wash the oyster shell chips before introducing to tank, to wash out possible dust, pollutions and their micro particles. Mind the grind size, too fine powder can cloud the water and clog the water pump. When use oyster chips as filter media, it's recommended to use a fine nylon mesh to stuff in first before loading into filter compartment, to avoid tiny chips to run away with running water.
Activated carbon aquarium filter media improves water quality by chemically adsorbing dissolved pollutant compounds derived from degeneration of the organic substances. In this way, Activated Carbon clarifies cloudy water, removes odors, and eliminates tannins that cause yellowing. It also removes medications, chlorine, chloramines, and certain phenols but does not address ammonia, nitrite, or nitrate.
Sintered glass bio-rings are high-porosity filter media that provide an exceptionally large surface area for beneficial bacteria to colonize, leading to highly efficient biological filtration and improved water quality in aquariums and ponds. Made from high-quality minerals, they establish a stable environment for nitrifying bacteria that rapidly process ammonia and nitrites, reduce algae by breaking down organic matter, and remain neutral in pH without altering water parameters.
Zeolite is a natural crystallized mineral of volcanic rock, that acts as an aquarium filter media by using ion exchange to absorb and remove ammonia and heavy metals from freshwater tanks. It is particularly useful for quickly reducing dangerous ammonia spikes from fish waste and uneaten food, but it is not a permanent solution as it becomes saturated and must be replaced.

Quartz Bio-Beads not only have a large effective surface area (8-20 times that of other filter materials) and an extremely permeable structure, but also contain a variety of elements such as calcium oxide, sodium, potassium, magnesium, etc., which is an ideal environment for nitrifying bacteria (aerobic and anaerobic). Therefore, it can cultivate extra multitude units of beneficial bacteria.

The rough, highly porous surface structure of biofiltration volcanic rock provides very good colonization conditions for purified bacteria. Since it is a natural product, the size of the granules and small pieces in the packaging is different for each piece. It can be washed and reused. It is suitable for both freshwater and seawater.
Expanded Clay Pebbles, universally known as LECA (Lightweight Expanded Clay Aggregate), are a staple in advanced growing techniques like hydroponics, aquaponics, and for improving soil. While expanded clay pebbles are not a direct "algae remover" like a chemical treatment or an algae-eating creature, they work by creating conditions that are unfavorable for algae growth.
Bio-sponge pad is a porous, cut-to-fit foam sheet that provides mechanical filtration by trapping debris and biological filtration by cultivating beneficial bacteria to break down waste. These pads are versatile, can be customized for various filter types, and help maintain a healthy and clear aquarium environment by supporting the nitrogen cycle. Its multi-porous feature will avoid blockages and provide the largest adhesion area for beneficial nitro bacteria. These bacteria break down toxic fish waste (ammonia and nitrite) into less harmful compounds, creating a healthy, stable environment for aquatic life and clarifying the water.

Hollow mineral beads are filter materials specially designed for aquariums. They have a variety of characteristics and effectively solve water quality problems. The hollow structure can form a special low oxygen environment, which is conducive to the reproduction of a large number of nitrifying bacteria, rapid bacterial cultivation and purifying water quality.
