Thks.
To complete my update, summary of changes since I started the tank;
-Added a BRS carbon / GFO filter unit (currently off line)
-light swapped out from DIY 6x39 T5 to power module 8x39 but only running 6x39 (got a killer deall, couldn't pass it up)
-Skimmer swapped out from Avast to RLSS R6i DC adjustable pump skimmer (I got mad at avast when the swappie crapped out, peg leg skimmer worked well, RLSS works better and uses less electricity)
-Return swapped out the iwaki 55 to a Reef Octopuss DC1050 adjustable (big energy savings, adjustable flow rate)
-Tank decline due to my own laziness. Let the vinegar/organic carbon dose run out, caused an algae bloom. Also let my kalk reactor run out of kalk and caused significant montipora losses. Gradually coming back. Kicks self....
