Receding coral....

[Snappy]

Stats:
Calcium 410
KH 12
PH 8.2
NH3 NO2 NO3 all 0

At 12 DKH your alk is getting close to being double that of NSW. I would tone that down to about 8dhk for a balance that will better match your calcium at 410. What is your magnesium level at?

here in calgary most of the LFS' sell coral snow, and i see that JL sells it a bit closer to you.

i would also get the pohls coral vitalizer .. works great with the snow.
