AquariumChatter.com — Reef Parameters

Water chemistry in your saltwater reef aquarium is extremely important.  Targeting specific numbers is not as critical as keeping your tank parameters stable.  If you want to adjust your aquarium’s water parameter make sure that you do it slowly.  Changing your parameters quickly is generally asking for trouble.  See the chart below for my recommended water parameter ranges.

Temperature ~ 77 to 83 degrees
Specific Gravity ~ 1.023 to 1.026
Alkalinity ~ 7.0 to 10.0 dkh (2.5 to 3.6 meq/l)
PH ~ 8.0 to 8.4
Calcium ~ 350.0 to 450.mg/L
Magnesium ~ 1200 to 1380 mg/L
Ammonia ~ 0.0 mg/L
Nitrite ~ 0.0 mg/L
Nitrate ~ 10.0...
