Has anyone managed to find open firmware for or gotten the Kessil X controller to recognize non-Kessil 5 channel lights? I know the 0-10 volt line control line is brand agnostic and works with pretty much anything, but I'm very interested to see if the controller can be made to work with Gen 2 HyperReef fixtures.

6.1 is incredibly low for sure, maybe a slow drip with a strong pH buffer? Removing CO2 is the only way to raise pH without also raising dKH, but you've got room to raise it a bit. Sounds more like the primary issue is the high CO2 concentration in the same room as the tank. This may be a bit out there but short of improving inside/outside circulation, Snake plants (S. trifasciata) and Areca Palms are incredibly efficient plants. If the CO2 levels in your room are really that high I bet those houseplants would grow like wildfire (and make a sizeable dent in the levels) with adequate care.
