Ca, KH too high

filbie70 · 08/03/2016, 12:18 PM

I'm running at 520 on Ca and 12 on DK. MG is at 1300. I turned my dosing off. It didn't push it out of range. I did a manual 2 part yesterday. I always understood that all 3 high would not stay steady state and the CA or Mg would precipitate out. What should I be looking for?

Thanks

Quit dosing until you get alk and ca down to about 440 CA and 11 or less for ALK. (I keep ALK at 7.8). Mag at 1300 is fine.

Those parameters are close enough to normal that you should be able to wait and let them drop on their own. If the tank suddenly turns grayish, that'd be a sign of precipitation, but I don't think the tank is even close to that level.
