Shirakura Liquid Mineral Ca+ adds vital minerals to the
aquarium water and raises its overall hardness (dGH). Especially when
using very soft water, a lack of minerals is well-known to occur quite
quickly and Shrimps might suffer from loss of colour and molting
problems. The important microorganisms in the filter and in the
substrate become inactive and the water quality decreases. A water
hardness (KH) of 0-2 is recommended for breeding bee shrimps, as is a
pH-value of less than 7 in order to avoid the formation of ammoniac.
However, achieving these values, the overall hardness (dGH) often gets
too low. In this case it is recommended to harden the water with
Liquid Mineral Ca+ in order to avoid the death of the shrimps. The
water hardness (KH) is not influenced by this. Mr. Shirakura furthermore
recommends maintaining an overall hardness (dGH) of 5 or more for a
healthy and strong skin.
Example of usage
For a new aquarium, add 5 ml (about 60 droplets) of Liquid Mineral
Ca+ per 10 l water. For existing aquariums with shrimps, add this
dose over several days. Prepare exchange water mixture beforehand.
1 drop of Liquid Mineral Ca+ to 1 liter water raises the
general hardness (GH) by about 1° dGh.
I have had great luck with 1ml per gallon to make a GH of 4-5.
