Nothing new to report. Did test for PO4 w/no color indication, so I'm assuming it's at low levels. Still seeing new growth and branches on most acros. I'll be backflushing the carbon this weekend, since I'm coming up on 1 month of use.

NO3 10meq/L
PO4 undetectable
PH 8.2 (problem with Ca reactor caused this)
Alk 9dKH
