Using kalk water only for topoff?

[stephane]

I have setup that tank ten years ago I have move it several time and even upgrade the tank from a 5 foot to a 6 but never restart the tank

maybe a real new tank dont react the same on PH as I have not realy experiment on new tank and calcium should be monitor beter but IMO
it is not a good id to dose any supplement on a new tank cause it take IMO more than 3-5 month to set up a reef and add coral to be safe and they dont realy grow fast at first

in a new reef PH never go down realy as well as calcium so addition should only begin when ph go down IMO and strart realy slowly
cause it is very easy to overdose

a new reef should last 1 years at lest on a kilos of kalk I dose it in 2 month
