Aquaforest Calcium 3500g
Aquaforest Calcium 3500g is a high-quality dry calcium supplement designed to maintain stable calcium levels in marine and reef aquariums. Based on calcium chloride, this professional reef supplement helps replenish calcium consumed by corals, coralline algae and other calcifying organisms, supporting healthy skeletal growth, coral development and long-term reef stability.
Ideal for reef aquariums, SPS systems, LPS coral tanks and mixed marine aquariums, Aquaforest Calcium can be used for regular calcium supplementation, one-off calcium correction or as part of a Balling method dosing system. The large 3500g pack size is perfect for reef keepers who prepare their own dosing solutions and need a cost-effective calcium source for ongoing aquarium maintenance.

Product Overview
Aquaforest Calcium has been developed for marine aquarists who need reliable calcium supplementation in reef aquariums. Calcium is one of the most important major elements in seawater, as corals and other calcifying organisms use it to build calcium carbonate skeletons and structures.
In reef aquariums, calcium is gradually consumed by SPS corals, LPS corals, clams, coralline algae and other marine organisms. If calcium is not replenished, levels can fall over time, leading to reduced coral growth, weaker skeletal development and less stable reef chemistry. Aquaforest Calcium provides a concentrated dry supplement that can be mixed into a dosing solution or used for controlled parameter correction.
Benefits for Reef Aquariums
Aquaforest Calcium helps support strong coral growth by maintaining one of the key building blocks of reef aquarium stability. Calcium is essential for hard coral skeleton formation, coralline algae growth and the health of calcifying reef organisms.
Maintaining stable calcium levels also helps support the balance between calcium, magnesium and carbonate hardness. In reef aquariums, these three parameters work closely together, so calcium supplementation should always be managed alongside KH and magnesium testing.
Suitable For
Aquaforest Calcium 3500g is suitable for:
- Marine aquariums
- Reef aquariums
- SPS coral systems
- LPS coral systems
- Mixed reef aquariums
- Clam systems
- Coralline algae growth support
- Balling method dosing
- Automatic dosing pump systems
- Aquarists preparing their own calcium solutions
- Larger reef aquariums with regular calcium demand
This product is designed for marine aquarium use and should be dosed according to test results and actual aquarium consumption.
How It Works
Aquaforest Calcium contains calcium chloride, which provides calcium ions for marine aquarium water. Once dissolved and dosed correctly, it replenishes calcium used by corals and other calcifying organisms.
Calcium is consumed continuously in growing reef systems. By testing regularly and dosing Aquaforest Calcium as required, aquarists can help maintain stable calcium levels and support healthy reef development.
How to Prepare
Dissolve 50g of Aquaforest Calcium in 1000ml of RO/DI water to prepare a calcium dosing solution.
Mix thoroughly until fully dissolved before use. Use clean measuring equipment and a clean dosing container. Label the prepared solution clearly and store it safely away from children, pets and direct sunlight.
For Balling method use, Aquaforest guidance for preparing Component 1+ uses 50g Aquaforest Calcium with 5ml Component Strong A and 5ml Component Strong B in 1000ml of RO/DI water.
How to Use
Test the aquarium’s calcium level before dosing.
Dose the prepared calcium solution according to aquarium demand and test results. Add slowly to a high-flow area of the aquarium or sump. If using an automatic dosing pump, spread the daily dose across several smaller additions to help maintain stability.
Aquaforest Calcium can also be used occasionally to raise calcium levels, but any correction should be made gradually.
Dosing Advice
A prepared solution made from 50g Aquaforest Calcium in 1000ml RO/DI water raises calcium by approximately 17.5–18mg/l when 100ml is dosed into 100 litres of aquarium water.
For one-off correction, 10g Aquaforest Calcium added to 100 litres of aquarium water raises calcium by approximately 35–36mg/l.
Do not raise calcium by more than 20ppm per day. Fast calcium changes can stress corals and destabilise reef chemistry.
Recommended Calcium Level
The recommended calcium level in many reef aquariums is approximately 380–460mg/l, depending on the system, salt mix and reef-keeping method.
Stability is more important than chasing a single exact number. Test calcium regularly and adjust dosing according to the aquarium’s actual consumption.
When to Use
Aquaforest Calcium 3500g is useful when:
- Calcium levels are lower than desired
- Corals are actively growing and consuming calcium
- A reef aquarium requires regular Balling method dosing
- SPS or LPS corals need stable mineral support
- Coralline algae growth is consuming calcium
- Calcium levels drop between water changes
- A dosing pump is being used for reef supplementation
- Preparing Component 1+ with Components Strong
- A larger reef system needs a cost-effective calcium supplement
Reef Stability Advice
Calcium should always be managed alongside KH and magnesium.
If calcium is difficult to maintain, test magnesium and carbonate hardness before increasing the dose. Magnesium helps support the balance between calcium and alkalinity, while KH provides carbonate ions needed for coral skeleton formation.
To maintain ionic balance when using Aquaforest Calcium as part of the Balling method, use it alongside Aquaforest KH Buffer, Magnesium and Reef Mineral Salt as required.
Compatibility Advice
Do not mix dry Aquaforest Calcium directly with KH Buffer or other dry supplements in the same container.
Prepared calcium solutions should be kept separate from KH and mineral salt solutions to avoid precipitation or unwanted chemical reactions. Dose each solution separately into a high-flow area and allow it to disperse before adding another supplement.
For Balling method systems, use separate clearly labelled dosing containers and dosing lines.
Safety Advice
Aquaforest Calcium contains calcium chloride and should be handled carefully.
Avoid contact with eyes and avoid inhaling dust. Wear eye protection where appropriate and wash hands after use. Keep out of reach of children. This product is intended for aquarium use only and should not be consumed.
Storage
Store in a cool, dry place away from moisture and direct sunlight.
Keep the container tightly closed when not in use. Avoid allowing the dry powder to become damp, as moisture may cause clumping and reduce ease of use.
