Hello
yea, seems i posted in wrong place. And seems i founded the answer by myself, but maybe its not correct so fewl free to correct me. Gmf would be better becouse it is more resistant but its all about pour size if i understan. Gmf what i could get was ~20 microns
not so close to 0.2
so it would be like free way to bacteria and other bad things, and dont think that solution would be clear at all.
