calicium hydroxide question

[phyto4life]

I'm using this to drip the kalk but it is a 2L not a G



I was going to buy some carbon in the next week from bulkreef supply

I already have kalkwasser

would 1/2 G of calcium chloride last about a year on a 30G?

can I drip dose it during the day 12 hours after dripping kalk the night before?

was going to order things from bulkreefsupply anything else that I should order for mag or alk etc?

Oceaniccorals.com (a sponsor here) carrys the exact same stuff. So there is no worries about customs etc.
