Alk confusion Help

[24storm]

So over the past few days my alk has dropped to 11 - 12 DKH
I mixed no water up 2 days ago with RO water and reef crystals and the new waters alk is 11 - 12 DKH ????

Is this normal?
How do i get it down?

Thanks Keith

How do i get it down?

Easiest way is to come over and buy more corals to use it up.

don't fret. between 8-12 is acceptable. ph is affected, so as long as these parameters are met you should be okay. i've heard of people using small amounts of an acid to neutralize kh should it ever get too high
