Crushed Oyster and Argonite

[AquaScaper]

:coffee2:

Well I've re-done the 30gal...the masterpiece was finally finished at 2am and I've decided that since my Coral reserves are low, I'd change things up a lil and see if I can get my hands on some Crushed Oyster or Argonite(sp) this time.


Where's a good source for either of those?

Aragonite is a morph of calcite - a calcium carbonate mineral. I don't know that I've ever seen it alone, but it is also found in Oyster (and other mollusk) shells. Commercially, Caribsea coral substrate boasts it.

So you're better off trying to find Oyster Shell of the two. The best source of that is farm feed stores I'm told, but I've never found a farm feed store close by. I would stick to oyster shell designed for feed use as it is a more pure form.
