Anyone using a kalk stirrer? Is there any benefit to using a reactor or stirrer over just adding kalk to your auto top off? I've always added kalk to my ato and used a dosing pump to add it to the tank. I have am aqua medic kalk stirrer 1000 that I never even took out of the box. I bought it a couple of years ago. I'm thinking I might want to set it up on my 90gal.
