Kalk Media 5kg

Aquaforest KalkMedia is a calcium reactor media for marine tanks, sold in a 5 kg pack. It is intended for reef keepers who run a calcium reactor and need a steady supply of calcium and carbonates for corals and other marine organisms.

Why it matters

• Granulation 5–12 mm: the grain size is chosen to keep water flowing through the reactor and to limit clogging during continuous operation.
• Calcium and carbonate supply: the media releases calcium and carbonates, which the manufacturer links to maintaining calcium, carbonate hardness and alkalinity levels.
• Trace elements: besides calcium and carbonates, the product contains additional trace elements that the manufacturer describes as supporting coral health and growth.
• Ready to use: the media is supplied ready for direct use in a reactor, with no preparation described by the manufacturer.

What it works with

KalkMedia is designed for marine aquariums that use a calcium reactor, and the manufacturer states it is suitable for reactor types in general. It belongs to the saltwater supplements and reef chemistry category, so it fits reef systems where calcium and alkalinity are maintained through reactor dosing rather than by hand. The data does not specify tank volumes, so check the reactor's capacity and the tank's demand before ordering.
