The highest concentrated 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 coral growth and for building skeletons. Due to the presence of carbonate ions, maintaining stable pH level is possible.
Dosage
10 ml of KH Plus solution raises carbonate hardness by 0.5 dKH in 100 l (27 US gal) of water. Maximum daily dose is 10 ml for 100 l (27 US gal) of water. 
Carbonate hardness in a reef aquarium should be about 6.5 -8.5 dKH.
Do not raise dKH more than 0.5 dKH per 24 hours. 
It is recommended to use a dosing pump to slowly dose KH Plus solution throughout the day
Please ensure your magnesium level is within the recommended range before attempting to raise or adjust your calcium and alkalinity levels.
Please remember, that maximum safe daily dose is 10 ml per 100 ltires of water. If you need a higher dose, split it into a few days.
