We have a bit of mystery with alkalinity. The Red Sea Reef Mature instructions say to calculate the amount of KH Coraline Grow to raise the alkalinity to 8.4 dKH, but no amount seems to budge the number much above 7. BTW our initial alkalinity was 10.0 dKH before starting the Reef Mature process. Today we discovered that it's precipitating as soon as it's dosed (as recommended) into the sump's pump chamber. My daughter stirred up the precipitate so that it would be conveyed into the DT but, as you will see from our testing on the next day, it's not moving the alk much at all.

This time we dosed the KH Coraline Grow directly into the DT and watched it precipitate immediately and float around the tank in little bits before settling or being skimmed. Is this at all normal? We don't know. You can see that the massive (but correctly calculated) dose on 1/6 barely budged the dKH, although the pH did come back up to 8.0. Hoping someone here has answers. If not, I'll move on to Red Sea Support.
