I’m having trouble finding information on cycling a saltwater tank with a sump and refugium. I know that you have to add copepods, macro algae, and the beneficial bacteria. My question is do you also add the beneficial bacteria to the display tank? Or do you just add it to the refugium and let the sump cycle the water.
