Reinstalled BRS GFO/Carbon reactor in sump/stand. Plumbed new lines from return stage, to reactor, and output into stage 1 from overflow and skimmer. Filter media inside reactor is a bag of Chemi Pure Elite.
Also did all parameter tests on water. Cleaned glass and power heads. Redirected Koralia pump and Koralia Nano for better flow.
Acan coral seems to be growing second head! All other corals seem to be okay.
