best way to add calcium kalk or calcium reactor?

was just wondering would it be best for me to add a calcium reactor or a kalk reactor?

i think that the calcium reactor will kepp the calcium more stable but can be ricky with adding co2 to system and the ph can do down.

the kalk can be very hazardous as a very high ph, but you add this for top up water that has evaporated, so best to have a container of fresh ro and then runn through the kalk reactor and to the sump where there is a shut off valve when the water reches the required height?

for my 100 gal which i hope to stock mostly with hard corals, like acros, montis, brain corals, trumpet corals, helifungia etc.

oh and what are the best bits to get for the calcium reactor and kalk rector?

all help very much appreciated, thanx andrew
