Domolite lime and other lost arts...

[Cazoom]

after going over all the posts does anyone ever use dolomite in their ca reactors or otherwise...
I was just given a 100 lb bag of dolomite (unused)
an older gentelman used as his sandbed mixed it with crushed corals in the 70's for his reef tank and had a few bags left in his garage he never used..
personally i wouldn't use as a sand bed.. but after all the reading i'd use a few cups in a filter sock to suppliment my tank once in a while to keep up my magnesium and calcium..( I have been doing this for a few months now)
wondering if anyone used in ca reactor as it seems to be a good media for that..
