Uses an upflow design to mix saltwater, calcium carbonate and CO2 inside a reaction chamber to eliminate the need for daily two-part dosing. Computer-precision engineered and utilize the latest aquarium technology to deliver unparalleled performance and value.
Media is kept constantly moving, so that it is impossible for channeling to occur and the whole of the media is utilized. Can achieve a dKh in excess of 80, which corresponds to a significantly higher calcium level.
Our top-selling, highest-rated Calcium Reactor. Superior quality. The lowest CO2 consumption of any reactor, meaning less impact on lowering the pH of your aquarium.
Attaches to any calcium reactor to help raise the pH of the effluent from your reactor.
If you are concerned about calcium levels due to your calcium loving animals look no further than our SRO calcium reactors
German made, top of the line internal or external water pump.
Offers a simple and convenient solution for maintaining calcium and alkalinity in your reef tank.
Master fabricated and computer cut, the KR620 is a very nice piece of equipment. One of the best ways to add kalkwasser to your aquarium. No additional supply pump, and is operational with minimum water level.
Creates saturated kalkwasser solution every time the feed pump is switched on to replenish evaporated water. Gentle mixing is achieved with a rotating sprinklerhead that is "powered" by the pressurized water feed. For aquariums up to 300 gallons.
High-purity, magnesium-rich mineral for traditional calcium reactors, or even blended in to pre-existing aquarium substratum, to gradually increase and maintain the magnesium concentration in the system.
A complete reactor media containing not only calcium and carbonate, but essential trace elements as well.
Zeolite - three different sized untreated and all natural Zeoliths of highest quality. ZEOmag Magnesium Granulate - pure magnesium granulate
Composed of fossil skeletons of reef building corals sustainably harvested from pristine sites in the Western Pacific. Replenishes calcium and carbonate alkalinity, strontium and trace elements.
