High-performance lime water reactor system with robust circulation pump for intensive mixing of the lime milk. Due to the extremely high calcium hydroxide loading, operation for up to several months without maintenance is possible.

pH value is slightly increased Calcium concentration is increased Phosphate concentration is reduced

Advantages over other lime mixers:

intensive mixing ot the suspension
sharp separation between white lime milk and clear lime water
gas-tight system: no ageing of the lime milk possible
free outlet enables a safe operation: check valve or adjustment devices are installed at the inlet and will not scale
continuous or discontinuous operation
sizes for all aquaria available
extrem high load capacity of calcium hydroxide
refill intervals up to some months
and of course

Required accessories:

feed with reverse osmosis water or very soft water
a drop counter helps with the adjustment

A suspension (mixture) of water and powdery calcium hydroxide is kept in suspension in the reactor by means of a robust circulation pump. Above this white lime milk is the clear lime water. The incoming reverse osmosis water (or very soft water) reacts immediately in the KWR with the calcium hydroxide to lime water, which runs back into the aquarium or filter tank.

The aquarium water is enriched with calcium ions. Due to the very high pH value of lime water (pH12-13), the pH value of the aquarium is also slightly increased. At the point where the lime water drips into the aquarium water, precipitates (hydroxyapatite) are formed which carry phosphate with them. This reduces the phosphate concentration in the aquarium (phosphate precipitation).
The carbonate hardness is generally not increased.

FAQ: Calcium hydroxide reactor - "kalkwasser" reactor

Calcium Hydroxide solution („Kalkwasser“) is a strong alkaline substance. Children should never reach the powder nor the solution. At contact with eyes or skin flush with much water and go to the doctor (take the label of the Calcium Hydroxide with you).
