What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.1174 dKH
To raise alkalinity by 1 dKH in 100 L: 8.5 ml.
Maker’s daily maximum: 13.2 ml per 100 L (13.2 ml for 100 L).
How it’s used
Test first. Basic: up to 5 ml per 30 US gal daily until target (7-12 dKH), then daily as needed. If below 7 dKH, up to 5 ml per 10 US gal daily. Maintenance ml/day = daily dKH drop / 3.1 x system US gal.
Cautions
• Contains carbonate/bicarbonate salts; harmful if swallowed, may irritate eyes/skin.
• Keep alkalinity changes within about +/-1 dKH; prefer daily over weekly dosing.
Sources
Potency and maintenance formula from Brightwell technical page; consistent with the 'divide by 3.1 dKH or 1.1 meq/L' maintenance rule. Multi-component buffer (carbonate, bicarbonate, borate); raises pH toward 8.3.
