I’m starting a coral QT and am planning to use aquaforest reef salt. My question is do I need to add bottled bacteria to the tank and seeded biospheres? My nitrates and phosphates will essentially be 0. Do I dose Seachem Reef Nitrogen and Phosphorus to bring the nutrients up so that the corals won’t starve? How often should you do water changes if alkalinity/calcium/magnesium are essentially still the same levels after 2 weeks in qt?
