I find your organizational skills disturbing.
Thank you?
That a badass fish room! Well done and also some kick *** hardware.
Thanks. I haven't used MRC before but the build quality seems to be pretty high. I'm trying to build this to last.
Short answer, carbon and phosphate reactors not completely plumbed in yet for the frag system.
Long answer:
I didn't do a great job of describing what the big picture is in this room. I'm going to have four major systems that can be run entirely separate if needed.
-main display system (kalkwaser, carbon reactor, phosphate reactor, calcium reactor, skimmer, refugium)
-frag system (carbon reactor, phosphate reactor, skimmer)
-coral QT (carbon reactor, phosphate reactor, skimmer)
-fish QT (carbon reactor, phosphate reactor, skimmer)
The main display will have the potential to be run in conjunction with the frag system by turning a few valves. They could share water for stability. That's probably how they will run a majority of the time, as one. I just wanted to put in the extra effort in the beginning in case I need to isolate things in an emergency. In the event of a major crash (my tank or a friends), I can always turn the frag system into a significant holding system and not have to do a lot of emergency plumbing.
The coral and fish QT will have the potential to be run in conjunction by tuning a valve. Similar mindset. I won't be treating the QT tanks with any chemicals that can harm the coral. If that needs to be done, a hospital tank will need to go up.
