Don,
It could be, I've talked with Randy about nitrates having a relationship alk.
He also told me that whether sand was hardened or not, I will hold in phos. and could leach back out.
Like you said, your new substrate could have a higher buffing capacity... :)
Either way:
Your reef looks great... ;Woot ;Woot
I need to test my N03 and P04 then. I haven't in months. Thanks Freddie!
