What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.056 dKH
Calcium
+0.4 ppm
To raise alkalinity by 1 dKH in 100 L: 17.9 ml.
Maker’s daily maximum: 25 ml per 100 L (25 ml for 100 L).
How it’s used
Start 5 ml per 100 L daily; raise by 2.5 ml/100 L per day once a week until KH holds at 7-8 dKH, then keep that dose. Check KH twice weekly and trim up/down. Typical 5-8 ml/100 L; max 25 ml/100 L/day.
Cautions
• Causes serious eye damage (H318)
• Ensure good aeration if no skimmer
Sources
Organic Ca and Mg salts + trace blend + organic acids (alkalinity comes from metabolised organic anions). Potency is only in the lab calculator, not on the label; Mg contribution unpublished. HTU: 500 ml supplies 100 L for up to 100 days (= 5 ml/100 L/day). Balancing: Ca low + KH ok -> add Elementals Ca/Sr; KH low + Ca ok -> add Elementals KH.
