calcium reactor and a Kalk reactor

[ROMADS]

What's the difference between a calcium reactor and a Kalk reactor? I just upgraded to RO/DI water and looking t add 1 of these. I have never used one and would like to hear what's the benefits of using them?

Thanks,

A calcium reactor dissolves aragonite with carbon dioxide gas. The reactor is hooked to a CO2 cylinder and a pump to circulate tank water through the system.

A kalk reactor doesn't really "react" anything. Its basically just a mixing container. It solubolizes Kalkwasser and slowly doses it into the tank. It uses a pump to stir a Kalk/water slurry and a dosing pump to slowly add the kalk water.

Both are excellent systems but require a lot of plumbing, pumps, and in the case of the Kalk reactor you need a source of RO water to hook up to the system. Because of this, they are usually limited to larger systems that have the room to handle the equipment.

I really like my calcium reactor. It is more expensive than a kalk setup, but it does not take as much maintenance to get it working. Once its dialed in, you really do not have to mess with it much. (just test your water once in awhile)
