What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.112 dKH
Calcium
+0.7 ppm
Magnesium
+0.16 ppm
To raise alkalinity by 1 dKH in 100 L: 8.9 ml.
How it’s used
Official directions not retrieved. Dose by test: about 9 ml per 100 L raises alk ~1 dKH with ~6.3 ppm Ca and ~1.4 ppm Mg (derived from stated strength). Start low and adjust to Ca/alk/Mg consumption.
Cautions
• Acetate-based: also acts as an organic carbon dose (bacterial growth, may cloud water or drop NO3/PO4)
• Hydroxide salts raise pH: dose slowly into high flow
• Directions not verified - confirm on the bottle
Sources
Calcium acetate + magnesium acetate + hydroxide salts; maker claims no salinity rise, no CaCO3, phosphate/silicate free. Potencies derived from the published approximate composition. The dealer page's Directions field is mis-pasted Genesis Rock text, and polyplab.com product pages were rate-limited (HTTP 429) for the whole session, so no official dose rate. Ca:alk = 70 mg per 4 meq = 6.25 ppm Ca per dKH (classic balanced deposition ratio ~7.1), i.e. close to balanced.
