KalkMedia – High-quality calcium reactor media for marine aquariums
KalkMedia is a premium-quality calcium reactor media, specifically designed for marine aquariums. With carefully selected granulation of 5-12 mm, KalkMedia ensures efficient calcium and carbonate delivery while preventing reactor clogging, guaranteeing long-lasting and stable equipment performance. This product supports the healthy growth of corals and other marine organisms by maintaining optimal calcium levels, water hardness, and alkalinity.
Ready-to-Use formula
KalkMedia is ready to use and contains not only calcium and carbonates but also essential trace elements necessary for maintaining a healthy aquarium environment.
What makes KalkMedia unique?

Rich in Trace Elements – In addition to calcium and carbonates, KalkMedia provides vital microelements that promote coral health and growth.

Water Parameter Stabilization – Regular use helps maintain optimal pH levels and water hardness, creating better conditions for marine organisms.

5-12 mm Granulation – Ensures smooth water flow and prevents reactor clogging, even under heavy system operation.

How to use:

Rinse the media in RO water before use.

Fill your calcium reactor with KalkMedia according to the reactor manufacturer’s instructions.

Connect the calcium reactor and ensure all tubing is correctly installed and secured.

Monitor CO₂ levels to ensure proper calcium dissolution and stable water chemistry.

Maintain reactor pH between 6.2 and 6.5 for effective calcium and carbonate release.

For aquarium use only. Keep out of reach of children.

Aquaforest Kalk Media for Calcium Reactors in SG

This 5kg KalkMedia is a calcium reactor media aimed at reefers who have moved beyond bottled two-part dosing and want a steadier, automated way to replenish calcium and alkalinity. The carefully graded granulation matters more than people realise, since uneven media packs poorly and channels, giving inconsistent effluent. For larger SPS-heavy systems in Singapore where coral demand is high and constant, a well-fed reactor takes a lot of the daily guesswork out of maintaining stable parameters.

In our warm 27-29C climate corals calcify quickly, so alkalinity can swing if your supplementation cannot keep pace. A calcium reactor running on quality media holds those levels far more smoothly than manual dosing during a busy work week. We suggest dialling in effluent slowly, checking display alkalinity and calcium over several days, and topping up the chamber before it runs low so you never get a sudden drop that stresses sensitive corals.
