Denny from Concept got back to me with following results:
alk : 8.53 vs mine 8.7
phos : 0.03 vs mine 0.08
nitrates : 0 vs mine <0.25
amonia: 0
calcium : 375 vs mine 430
My biggest concern Caclium and PO3 are big difference. What is the most accurate Test kit for PO3 and Calcium? Still my SPS are upset so should be a problem somewhere. Ideas?
