From another thread...
I did not say bentonite would be better. I just said that I thought it would make more sense (to me). Zeolite types are more complex than I've had time or interest (so far) to understand very well, though I thought that some zeolites adsorbed aluminum, so my understanding was that adding assumed Calcium bentonite while using zeolites would be of no concern. I know little of bentonite, but reading about it's abilities seems to line up with Zeovit's claims of Coral Snow. So it made sense to me when a few someones told me it was bentonite. I never researched it further.
This is the thread you refer to I assume? http://www.reefcentral.com/forums/showthread.php?t=2509907
Interstingly, "reefvet" replies to your thread, with no actual data mind you (claiming it is clay, assuming he means bentonite), though I wonder if he did his own testing (he's a biologist).
Seeing as our tanks are full of Calcium carbonate, why would there be any benefit to adding very finely ground Calcium carbonate powder mixed with RO? What's the science behind that? Flocculation from attraction of positive charges?
I've heard some people say that Coral Snow is likely Calcium bentonite. I'm not sure if that's true or not, but wouldn't that make more sense than Calcium carbonate?
It is carbonate, I've done simple analysis and posted in Reef Central some time ago. May be is good to start new thread here. Actually it is chalk, not pure calcium carbonate (there are some magnesium etc.) and it is about 400 grams in 1 liter RO water.
Way do you think bentonite is better than calcium carbonate? Bentonite is aluminosilicate just like zeolite and I don't really think it is good idea to spread fine particles containing aluminium in a reef tank.
