So I'm still pretty new at this but hopefully others will correct me if I'm wrong. A lot of the parameters depend on what is in your tank. I've also read that the most important part of parameters is consistency..
Ammonia: 0 ppm
Nitrites: 0 ppm
Nitrates: as close to 0 as possible.
Specific gravity ( which is basically salinity)
1.023-1.027 (on the higher end for corals... This is a very wide range many would say... So try to stay with 1/100th of your starting reading)
Calcium: 400-500 ppm
Temperature: ~80... But really depends on what is in the tank.
Hopefully others will chime in!
