Quick? What is the obsession with quick?
Quick is not synonymous with clean, with pure, with anything... its just "quick."
Patience pays. Period. Most things that take a little time to do are worth the time it takes to do them. And if you seriously think that you can dissolve todays OTC pseudo products with dH2O and remove the gakks with a polyfill acquarium filter, you are in for a nasty surprise. You may not have this surprise until after the reaction. But you will have that surprise.
Sorry, but it isn't that easy, and water isn't going to cut it today. Acquarium filters or not. Quick in this case also means dirty, not clean.
If you haven't discovered the fact yet, you need to know that a good many of the binders and gakks that come with pseudo are very water soluble and dry to a nice, crunchy white powder. It has pseudo in it. It isn't all pseudo. And you do not want what isn't pseudo in your reaction.
I assure you that if pill extraction was that simple, and that easy, you would not have been the first to have discovered it. Think about it.
