KH Power Dupla Marin reliably raises the carbonate water hardness and buffers the pH value in seawater aquaria. Carbonates are constantly consumed by lime consuming species such as hard corals, molluscs, hard tube worms, various calcareous algae as well as by biogene decalcification. Avoid large pH value fluctuations and an insufficient supply to lime building organisms by regular dosage. Dupla Marin KH is readily soluble and does not cloud the water. The carbonate hardness in seawater aquaria should be between 7 and 9 KH, the optimum lime content is between 380 and 400 mg/l, the optimum magnesium content at 1,350 mg/l. These values must be regularly monitored in your aqaurium.
Dosage. One level measuring spoon (included), equal to 10 grams, raise the hardness of 100 liters of water by 4.0 dKH. Due to the individual number of specimens and spcies, every aquarium has its own requirements to which the daily dose has to be adjusted.
