How it’s used
Measure Ca and Alk to find the need, then sprinkle level spoonfuls (use the scraper) onto the water surface while stirring, one at a time once the previous one has dissolved. Keep KH at or below 9 dKH.
Cautions
• Max 2 spoons per 100 L per day
• Do not exceed 9 dKH
• Undissolved crystals must not land on corals; add one spoon at a time to avoid clouding
