Best Calcium additive

[michika]

I use Seachem's Calcium (powder form), and while it works, I am not impressed with the powder form. When I open the jar, and scoop out product it often leads to small powder clouds.

I also have Seachem's liquid version, although it is only supposed to maintain calcium. I find that the cost isn't justified for this product.

In general I find the powered product works better, and is more cost efficient. The trade off is that it is messy to work with, and it makes me uncomfortable to know that I'm breathing in chemicals.
