50/50+ tek - use of Calsium Sand
    #14580526 - 06/08/11 03:54 PM (12 years, 7 months ago)

I've just started a few casings after a few years layoff and have a question regarding the 50/50+ recipe.

I've always thought I've been following the recipe correctly until I've done some more reading - now I'm confused.

tek:
15 1/2 cups vermiculite
15 1/2 cups peat moss
4 1/2 cups crushed oyster shell
1.2 cups of hydrated lime

Then there is a statement that questions the use of hydrated lime, and says to use calcium carbonate instead.  I had read it to insinuate that I replace the 1.2 cups of hydrated lime with 1.2 cups of calcium carbonate.  Thus, what I've been doing is adding 15% crushed oyster shell and another 4% of All Living Things Calcium Sand (which claims to be pure calcium carbonate).  I've always thought my yields have been okay, although, usually I get about 3 flushes before succumbing to mold.

Now the more I read, I'm thinking I'm wrong.  Is the crushed oyster shell and the calcium sand the same thing? 

Does anyone have any experience in using "All Living Things Calcium Sand" purchased from Petsmart?  If so, should I use this instead of the crushed oyster shell (as opposed to in addition to it) --- and furthermore, how much should I use?  I just bought a big bag of it.  Should the quantity of the calcium sand that I use be the same as what 50/50+ calls for with crushed oyster shell?

Thanks for your help.
