i waited about 8-9 hours and let it settle and then drained the intile thing through a coffee filter, that takes about 1.5 hrs, then filter the waterman filter and bake and you are done. here a very important tip that i learned, before you put it through the waterman filter put the bollt with the solution in coffe hot water to warm it up and keep in there until it is filtered, also do not let any air in the waterman filter and also usea 3 cc syringe because you get more pressure than a 10 or 5 cc one. hoply you have an extra waterman in case it cloges. good luck.
