What one dose does
PARAMETER
1 ml / 100 L
Calcium
+0.43 ppm
Alkalinity
+0.06 dKH
To raise calcium by 20 ppm in 100 L: 46.5 ml.
Maker’s daily maximum: 25 ml per 100 L (25 ml for 100 L).
How it’s used
Dissolve 6 level scoops (~140 g) in ~900 ml RO water to 1 L (700 g -> 5 L). Dose the solution: start 5 ml/100 L/day, +2.5 ml weekly until Ca and Alk stable, max 25 ml. Use Ca as the regulating test.
Cautions
• Do not exceed 25 ml per 100 L per day
• Set Ca/Alk/Mg to target first (Tropic Marin suggests Original Balling A for Ca, Part B for Alk, Bio-Magnesium for Mg)
• If Ca and Alk drift apart (non-coral consumption), correct with the single-element products per Tropic Marin's correction chart
• Effects are per ml of the mixed solution
Sources
Manufacturer states 1 kg powder = 307 g Ca and ~43,000 dH; per g of dry powder that is 3.07 mg/L Ca and 0.43 dKH per 100 L (derived). One-part balanced Ca/Alk (organic calcium salts), no NaCl by-product, pH-neutral per Tropic Marin. Start 5 ml = ~2.15 mg/L Ca + 0.3 dKH; max 25 ml = ~10.75 mg/L Ca + 1.5 dKH.
