What one dose does
PARAMETER
1 drop / 100 L
Iodine
+0.01 ppm
To raise iodine by 0.02 ppm in 100 L: 2 drops.
How it’s used
1 drop per 100 L daily; target iodine about 0.06 ppm.
Cautions
• Per-drop strength is ~15x the Lab Iodum per ml (1 ml -> 0.01 ppm) if 15 drops/ml; verify before large doses
Sources
Conflict: if Aquaforest's own ~15 drops/ml applies, this implies ~150 ug/L per ml per 100 L, vs Lab Iodum 10 ug/L per ml. One of the two pages may be in error.
