I was reading about fining agents and noticed that 'Sparkolloid' is diatomaceous earth. I have used diatom powder (a highly refined grade of diatomaceous earth) in aquarium filters to polish the water. Can this same powder be used to clear wines by mixing it in, and allowing it to settle? If so I have a 5lb bag that I could start using.
Thanks

Sparkolloid is _not_ diatomaceous earth. I don't think diatomaceous earth will clarify your wine unless it is used in a filter.
Don't just dump DE into your wine. It's not a fining agent; it's a filter aid. Also, some brands of DE need to be washed first to rid them of cardboard smells.

In theory, it isn't a bad idea using a diatom filter to fine your wine as it a great water polisher. I have seen aquarium water go from murky brown to crystal clear in minutes. Although, Diamtom powder (i.e. the power used for Diatomaceous earth filters) is a great water polisher for the aquariums, it may strip your wine more than a wine fining agent. As well, there are links between Diatomacious earth and lung cancer probably because it is 80-90% silica (silicon dioxide.) Be careful and always wear a mask!!
