I think these are excellent numbers for any reef aquarium. Personally, I keep Alk at ~8 and no3 undetectable with hobby testing resolution. My actual no3 is ~ .1 ppm with lab testing resolution.Here are the parameters that we typically recommend and pulled this list from our blog on coralline
- Nitrates <1.0 ppm.
- Phosphates <0.05 ppm
- pH values of 8.2-8.3.
- Alkalinity ~10 dKH.
- Calcium 415-425 ppm.
- Magnesium ~1,250 ppm.
- Potassium ~400 ppm.
- Total iodine ~0.06 ppm
