Aquaforest KH Buffer Dry is a concentrated powdered alkalinity supplement designed to maintain and increase your saltwater aquarium's dKH level without introducing additional elements. This essential addition supports calcification and coral growth by ensuring that corals have the necessary calcium and alkalinity in their environment for healthy skeletal development. To prepare the solution, mix 80 grams of KH Buffer Dry with 1 liter of RODI water, stirring vigorously before allowing it to sit undisturbed for 24 hours. Recommended dosing starts at 5 mL per 27 gallons daily, adjusting as needed based on aquarium test results.
