I have been slacking on my testing. Today I did my water tests... everything checked out but my Calcium and KH. Calcium was at 700 my KH was at 6. My question is my high calcium reading afecting my KH? I used to have my Calcium around 420-460 and KH used to be 8-9. What is the highest acceptable calcium reading for a reef? As always thanks for the help.

It is likely affecting your KH.
If I go two weeks without checking kH it is normally low, about 7.
