What one dose does
PARAMETER
1 ml / 100 L
Alkalinity
+0.0278 dKH
To raise alkalinity by 1 dKH in 100 L: 36 ml.
How it’s used
Make up each part with RO water (1000 ml pack to 10 L). Dose all three equally; start 5/10/25/50 ml per 100 L/day (new/soft/mixed/SPS tank) or from KH use (36 ml/100 L per dKH/day), then adjust daily from KH.
Cautions
• Dissolve the whole pack; a powder blend is not uniform
• Keep 5 minutes between parts; never mix parts together
• Bring KH to 7-8 dKH before starting (3 g NaHCO3 per 100 L raises 1 dKH)
Part of Essentials (3-part)
Sources
Discontinued (2015-2018 era). #1 is a dry blend of carbonate sources. The manual equates the working solution to 84 g NaHCO3 per litre: check 36 ml x 84 g/L = 3.02 g NaHCO3 = 36.0 meq -> 0.36 meq/L in 100 L = 1.0 dKH.
