That's exactly it. If you are having a hard time getting you Ca or Alk levels to where they should be, check your magnesium it's probably too low.
great--thanks for clearing that misconception up for me.
If the level of calcium are really high in this reefers tank, and assuming they are not using a calcium reactor, would that be a good indication that magnesium levels are low?
Thanks
