What one dose does
PARAMETER
1 ml / 100 L
Boron
+0.0568 ppm
To raise boron by 0.5 ppm in 100 L: 8.8 ml.
Maker’s daily maximum: 0.26 ml per 100 L (0.26 ml for 100 L).
How it’s used
Target 4-6 ppm (seawater ~4.5); max sustained 8 ppm. Raise no more than ~1 ppm per day. If below 1.5 ppm, up to 1 ml per 100 US gal daily until 4-7 ppm. Maintenance ml/day = daily ppm drop / 1.5 x US gal.
Cautions
• Watch alkalinity and pH; borate adds to total alkalinity readings.
• Do not sustain above 8 ppm boron.
