Kalk how to use it and should i?

[Scavenger]

Some reefers advise not adding any kalwasser or any additives to a new reef. Once the reef is established, monitor calcium levels and only add kalc once the initial natural supply starts to diminish. I sort of followed this and only started doing kalwasser in top off when I noticed my coraline algae growth rate slow considerably. This worked for me, but all reefs are differant.
