What one dose does
PARAMETER

Alkalinity
+0.1429 dKH
To raise alkalinity by 1 dKH in 100 L: 7 ml.
How it’s used
Bring KH to 7-8 dKH first. Start both parts at the same dose from daily KH use (7 ml/100 L per 1 dKH/day). From day 4 adjust both by 5-10% when KH falls or rises; from day 7 tune Pro 2 to Ca.
Cautions
• Dose Pro 1 and Pro 2 separately; do not mix
• Store upright at room temperature
Part of Essentials Pro
Sources
Discontinued in Germany; succeeded by Essentials Mixed Reef per a German retailer ('ehemals Essentials Pro') and ATI's calculator factors (Pro = 0.71x SPS volume, i.e. Mixed Reef strength) (same 14,000-14,250 dKH/L and 100,000 mg Ca/L). CONFLICT: some US distributors now sell Essentials SPS (10,000 dKH/L, 74,000 mg Ca/L) under the 'Essentials Pro' name/URL - identify the bottle by its stated concentration. US retailer (BRS) start doses: 0.8 / 2 / 4 ml per 10 US gal (low / mixed / heavy demand), equal parts.
