question for all you chemists out there (calcium hydroxide)

[Buccaneer]

So what hardware store and what is the brand of lime-mix you are using ?

I got a big 20kg bag from Totem Building Supplies here in Lethbridge (it's like Home Depot). The brand is called Graymont (on the bag it says: High Calcium hydrated lime type "N")

Thanks ... have you done any testing of your tank parameters before and after dosing ?

I think what you are going to find is commercial lime often contains impurities, e.g., silica, iron, alumina, and magnesia. If you can find a bag that has a guarenteed analysis your ok.

the stuff you are looking at looks like a left over hog pog of chemicals.. one concern I have is that Calcium carbide reacts with water, releasing acetylene. could get a lottle flamable around the tank
