Seachem Liquid Marine Buffer
Liquid Marine Buffer™ will safely raise marine pH to 8.3. It will not raise pH above 8.3 even if inadvertently overdosed. Liquid Marine Buffer™ is a blended product and is not just sodium bicarbonate or sodium carbonate, commonly sold as a substitute. Such products can raise pH to dangerous levels if not used properly. Liquid Marine Buffer™ contains sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate. Sizes: 250 mL
Liquid Marine Buffer™ shares the same blend as Marine Buffer™ powder; thus, it confers the same benefits. It is a blended buffer that drives and holds your pH at 8.3 because of the blend. The pK of Liquid Marine Buffer™ is actually slightly higher than 8.3 in order to combat the influx of bicarbonate at every water change.
Use 1 capful (5 mL) for every 20 L (5 gallons) daily until pH stabilizes at 8.3. (Note: The 2 & 4 L container’s cap is 10 mL). This may take from a day to a week depending on original pH, alkalinity and buffer system balance. Thereafter, use as needed to maintain pH.
