Kaldnes K1... 

[Rob Nash]

kaldnes is used in aquariums to keep the alkalinity up, usually in salt water aquariums.... please explain your purpose for wanting to include one in an ap system.

kaldness doesn't have anything to do with alkalinity, it's neutral.. it's used to provide surface area for bacteria, and the moving bed action helps breakdown solids, oxygenates the water, and strips co2
