Dave, I missed you at the meeting I brought the Pse. Saulosi for you but you were not there. Maybe I can bring them to you this week? or sometime on the weekend? What do you use in your tanks to buffer PH? just the coral substrates?? I would love to get some different ideas, I think I may have had a bad bunch of crushed coral to have it break down. I got it in Michigan at LFS.

I just don't trust bicarbonates in general. CaCO3 should be ok, if you can get it to dissolve. dave
