I use a PM kalk reactor which uses a MJ400 instead of a stir stick. However, the MJ is not immersed. I have had mine running for about 18 months with no problems yet. I do anticipate replacing the impeller as these will break down over a period of time. The MJ's are epoxy encased so water will not penetrate. However, I do not know what the impact of kalk would be on the body, so I personally would be hesitant to immerse it.
I do run my kalk in line with my RO. The MJ moves the water from the top off container through the kalk reactor and into the sump. This has worked well for me.
