It's unlike CaCl will affect your pH, unless you overdose it
to a point the calcium starts to percipitate with the carbonate.
However, some form of calcium carbonate (crush coral, aragonite, etc)
will be easier to handle even though they increase carbonate hardness.
The reason is calcium chloride is quite soluable and there is a
chance of overdosing, while calcium carbonate is very hard to
dissolve. You can simply leave a bag of calcium carbonate in the
filter or the tank and check the hardness from time to time.
