A week ago I changed my 2 part so that they were equal volumes, they were a bit out of whack. I have to admit I haven't felt like I've been able to reach consistent levels. I blame myself for that. I've always seemed to struggle to keep my Alk up. If I want a CA of 425 what should I expect my ALK to be? My heaters had some precipitation on them but nothing I thought was abnormal. I cleaned them a month ago, for the first time in forever, and they haven't accumulated any since. They are the cobalt black heaters so it would show up easily.
