Just a quick question, and maybe I am reading too much into it but here it goes. I had supersaturated carbonates ultimately caused by GFO. I no longer use GFO (leason learnt!). I have been trying to permanently liberate my system from saturation (by saturation I mean not being able to exceed alk 8dkh and ca 400). For obvious reasons, I want to get alk to 11dkh, ca 420-450. I have been using baked baking soda to raise alk in conjunction with a ca reactor I run every other day. I use a 6:1 ratio of baked baking soda to non-baked because I like the higher ph effect.
Question is: I have noticed that as time progresses, the saturation point of the water column seemingly gets lower (meaning 3 days ago I had alk 9dkh ca 440), now I can only achieve 8 dkh ca 400. I read one of Randy's articles on Calcium and it really got me wondering in that a water column's carbonate/ bicarbonate ratio effects the water column's overall point of supersaturation, when bicarbonate shifts to carbonate, it lowers the supersaturation point. In sum, by adding a mostly carbonate mix here, is that what is causing the point of supersaturation to become lower?

You missed in your post that pH is also a controlling factor in those saturation rates.
