Hi Houston,

Where can I buy calcite granules for water treatment? They usually come in a 50-lb bag and are used in an acid neutralizer, to bring acidic well water up to a normal pH.

It's just pieces of clean marble. I'd like to find it for $20-35/bag and am willing to pick it up locally. I'm aware it's online for $54-100/bag, with shipping accounting for about half of the cost. I need 4-5 bags (each is 0.5 cubic foot).

​

I've checked with the following supply houses:

• Culligan: $48.50/bag
• Grainger: $60/bag
• Pumps of Houston: I have a call in to them.
• Morrison Supply: $45+shipping, 3-4 week lead.
• Ferguson: Used to carry it locally, but no longer. Now it would be shipped from AL, CA, etc.
• Quality Home Products (Rainsoft dealer): Doesn't have it.
• Moore Supply: Doesn't have it.

I've checked with these suppliers:

• Lancaster Pump: Refers to Ferguson.
• Columbia River Carbonates: Refers to Pumps of Houston.

Here are some references so you can see what I mean:

Specifically, is the reptile/amphibian house open? It's planned to close "for a few weeks" "mid-February."

(Yes, I thought to call them, and am on hold with them now, already at least 30 minutes.)

Background:

I understand there's a lot of construction at the Houston zoo, and will be for a couple more years.
