What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.034 dKH
To raise alkalinity by 1 dKH in 100 L: 29.4 ml.
How it’s used
Same Foundation routine as the liquid. Add powder directly or make stock solution (1 kg in RO water to 10 L); note the stock is much weaker per ml than the retail liquid.
Cautions
• Max daily rise: Ca 20 ppm, Alk 0.5 meq/L (1.4 dKH), Mg 10 ppm; spread larger corrections over several days
• Add in order Magnesium -> KH/Alkalinity -> Calcium+, allowing 10 minutes between each
• Add to the sump or a high-flow area, away from fish and corals
• If a level is above target, pause until it is consumed, then resume at the amended dose
• Homemade stock (1 kg/10 L) delivers 0.034 dKH per ml/100 L vs 0.1 dKH for the retail liquid: do not swap them 1:1
