Will this work to balance pH of casing

I'm using peat and verm to case my substrate. Will this work to balance my pH? NOW Calcium Carbonate
I don't plan on buying it off eBay but I saw it in the store for cheaper. It's says calcium carbonate and it's in powder form yet they sell it at vitamin and health stores. Will it do the trick?

Get some hydrated lime, oyster shell flour, and gypsum.
Use 5% oyster and 5% gypsum by total volume, and 2.5% lime by the volume of peat used.
About a teaspoon of lime per cup of peat, approximately.
Your starting pH should be around 7.2-7.5 ideally.
The HyLime will go to work immediately, the oyster will slowly raise the pH, and the gypsum will provide a buffer for wild swings either way.

I can't find hydrated lime anywhere. The only lime I saw is dolomitic lime and garden lime which had lots of other crap like magnesium. Why would what I found work? It should be soluable and it's pure CaCO3.

Oyster shell flour = Calcium Carbonate.
Calcium carbonate is quite slow at changing the pH but longer lasting, while Hydrated Lime is nearly instantaneous.
If you can't find Hydrated Lime, calcium carbonate is better than nothing and certainly better than dolomitic lime, which is a big no no.

Lime IS calcium carbonate. You don't need food grade. Check a nursery. RR

I've gone everywhere and can't find lime. As long as the food grade CaCO3 will instantly adjust my peat, then I'm willing to pay a little more for it than hunt the rest of my life for horticultural hydrated lime.

Hydrated lime is calcium hydroxide Ca(OH)2 while calcium carbonate is CaCO3 and is the active ingredient in agricultural lime.

look for an agricultural supplies store in your area.

I hope this settles the chalk dillema. Straight from Crayola (you can also use Prang)
Crayola manufactures two types of chalk, extruded and molded. Extruded chalk, such as Crayola Anti-Dust White Chalk, primarily contains calcium carbonate. Molded chalk, such as Crayola Children's Chalk (available in white or colored), is a softer chalk, made of plaster of paris. This type of chalk is not dustless and not recommended for chalkboard use.
You can use the white chalk, or the anti dust chalk. The chalk is 95% pure calcium carbonate. only cost $2.

By it's all lime, I meant from limestone. Different processes go into manufacturing the various types. RR

Use Hy-Lime for fast pH adjustments up, oyster for long term release, and gypsum to prevent wild swings either way.

Use Hydrated Lime for fast pH adjustments, calcium carbonate (oyster) for long term release AND to prevent swings and gypsum as a nutritional supplement, with the added advantage that it helps buffer swings.
