You may be a little confused.
is used to maintain calcium and alkalinity. Adding kalk
will not drop your alkalinity levels, but your magnesium and strontium levels can drop since kalk
doesn't really have either of those in it and they can get used in the calcification process.
Limewater is one of the most useful solutions for aquarists looking to maintain calcium and alkalinity
in reef aquaria. I have used it for many years to supply my reef aquarium system. It can be inexpensive, is not too difficult to use, and can maintain the pH of reef aquaria even when it is otherwise reduced by calcium carbonate/carbon dioxide reactors or excess carbon dioxide in home air. Limewater does, however, have a number of eccentricities that aquarists need to be aware of when using it. These include high pH, limitations on how much can be added based on evaporation rates, and considerations of what else is or is not dosed along with it (such as magnesium)
Despite old beliefs that using of limewater depletes magnesium, the truth is somewhat more complicated. As was shown above, magnesium is not dosed in typical settled limewater because it is insoluble; nor is it present in very high concentration even in undissolved lime.
Using limewater can also deplete strontium
, not because it is insoluble in limewater, but because there isn’t much in at least some brands of lime
. Since strontium may or may not be beneficial, this may or may not be a concern.
