NOTE: Depending on specific gravity, alkalinity should be about 4.0–5.0 meq/L, calcium should be between 380–430 mg/L, magnesium should be between 1200–1350 mg/L, and strontium should be 8–12 mg/L. Between water changes some elements may become depleted through utilization. Seachem offers a full line of reef supplements for restoring and maintaining many parameters, including (but not limited to) calcium, magnesium, strontium, iodide and alkalinity. |
