Wanted to see if other people know that nitrates dont infact hurt your water quality, i have had reefs and fish only with high and low nitrates and i have never had any fish or corals die off infact ever tank thrived and corals grew as normal. The only perimeters i believe need to be monitored in a reef is temp, nitrite, calcium, alkalinity, ph, ammonia and for fish only, copper (if being used) ph, ammonia, and nitrite
