How it’s used
Single-dose correction of low Ca (and Sr) toward 380-420 mg/L Ca / ~8 mg/L Sr, based on a test or ICP. Do not exceed 25 ml per 100 L per day; split larger corrections over several days.
Sources
Calcium + strontium salts with biopolymers. The lab Elementals calculators list Ca targets but contain no Ca formula. Ready2Reef HTU recommends it for correcting low Ca on Ready2Reef systems.
