What is it you need to know about the topics you listed above. Lets get a discussion going!
I for one wouldn't mind knowing why some of my SPS (caps and digi) are doing great while other acros are kind of blaw. They have great polp extension but don't color up as nice as they should.
Ca=380-420 on average
ALk= 2.5-3.5 Meq/L sometimes it dips to 2.0
MG=unknown, can't get a test kit in Calgary. Just add a squirt weekly
Lighting=400 watts, 14K
Temp=81-82C
PH=8.1-8.2 average during day
This Prostrata should have blue tips
