I've recently purchased a 2.5KG bag of "Garden Lime" from Richgro. From
my experience so far, Lime is made of Calcium compounds and is a
flowing, white powder. With the stuff i have, not only is it not the
nice lime that i wanted, its not quite "powdered", is coarse, has some
strange black particles and what seems to be some sand in it. Shouldn't
have been a cheapskate and purchased the cheaper type...

Does anybody have any experience with this brand and this type of
"Lime"? Is it normal for it to be like this or should i go back to
Bunnings and get a refund?
