Aquaforest kH Plus 250 ml Solution increasing temporary hardness level in marine aquariums Solution for raising carbonate hardness in marine aquariums. KH Plus was created for maintaining sudden carbonate hardness drops and restoring the ionic balance in the aquarium. The proper value of carbonate ions is necessary for healthy corals growth and for building skeletons. Due to the presence of carbonate ions maintaining stable pH level is possible. 10 ml of KH Plus solution raises carbonate hardness by 0.25 dKH in 100 l (27 US gal) of water. Carbonate hardness in reef aquarium should be about 6.5 -8.5 dKH. Do not raise dKH more than 0.5 dKH per 24 hours. Please ensure your magnesium level is within the recommended range before attempting to raise or adjust your calcium and alkalinity levels.
