What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.1 dKH
To raise alkalinity by 1 dKH in 100 L: 10 ml.
Maker’s daily maximum: 14 ml per 100 L (14 ml for 100 L).
How it’s used
Use instead of KH/Alkalinity during cycling of new tanks and long-term in fish-only/soft-coral systems; aim ~3 meq/L (8.4 dKH). Find the 4-day alkalinity drop, divide by 4 for the daily dose, retest weekly.
Cautions
• Max daily alkalinity change 0.5 meq/L (1.4 dKH)
• Do not use together with Foundation ABC+
• Dose other K or Fe supplements (e.g., Potassium+, Iron+) only to measured uptake
Sources
Potency from retailer label transcription; the manufacturer leaflet (manuals.plus copy) confirms the 100 L/25 gal chart basis and the 1.4 dKH/day limit but its text does not restate the 0.1 dKH figure. maxDose derived.
