Well I checked the Alk this morning and it was back down to ~8.2 DKH. It seems to begin to fall, from the time of the dose, to the next morning. Just doesn't make sense how it can go from ~10.2DKH to ~8.2DKH in a 24 hour period.
So new plan...
As soon as my Kalk resevoir is empty, I am not going to make any more up and will switch to using 100% pure FW for topoffs. The only thing I can come up with is that the Kalk is somehow messing with the chemistry. I don't see how it could cause an Alk problem. If anything it would be putting more in. Steve had suggested I stop with the Kalk before, but my Kalk container was still full then. Now that it is nearly empty, I'll hold off on the Kalk, begin doseing the buffer, and try again.
I looked at my heater in the sump, and while it did have precipitation on it, I don't think it excessive. I did a "spot" check on one of my pumps last week and it showed no signs of precipitation.
BTW, I checked the Mg level, it came out to 1350 according to the Seachem test kit.
