Dez, can you explain that cal thing again??

Hi Dez,

I'm finding that I'm having to add 2 cups of C-balance everynight to keep up with the calcium levels. It's getting slightly expensive, but so very easy to do. When I was at your place and you showed me that "thing" that dripped kalk into your tank, what is it again? and do I need a pump for it as well? Could you hook me up with one? how much are they? explain again, thanks (you know I'm kinda daft when it comes to the equipment part!)
