Hi,

Colour ?

CaCO3 = white
MgCO3 = white
Al2O3 = white (I should know, I lived near a Alumninum smelter for 17 years. This stuff is gross when it is all over you car. )
NaCl = white
SrO (this really doesn't exist like this) = SrCO3 = gray-white when expose to air.

I think we still need a better explaination.

Darren,

I wonder if there is a titanium or platnium excavators or backholes ? Then we would be sure that none of the metals used in processing would be harmful to our tank. Just kidding [img]images/smiles/icon_smile.gif[/img]

You have to give it credit that Domolite has been use for a while.

Yes, domolite will dissolve at 7.0. Only thing is that the domolite has to be at a pH of 6.0 to dissolve at the same rate as calcite. So, it is going to dissolve very slowly. BTW, I worked out the numbers and calcium carbonate will start to siginifcantly dissolve at a pH of 7.4. For magnesium carbonate...6.4.

I guess time will tell who is right. Wish me luck !
