Finally installed a Reef Octopus calcium reactor on my 180 display tank. I don't have the CO2 turned on yet, but the circulation pump is running and Kamoer feed pump is running near full speed at 100ml/min. to purge.  The display immediately became super cloudy, even though I pre-rinsed the media in RODI water.  Guessing this is normal?  Any idea how long before it clears up?
