Hey Bro,
I agree whole heartedly with G-S. I've made in excess of 60 4gr Kits of fina and, from my experience if you heat the pellets while in BA to quicken the disolving process you will always get a product that looks like automatic transmission fluid. The sedement at the bottom of your vial probably formed after the filtrartion process, didn't it? Don't worry, this will always happen if the BA is heated with the pellets. I would suggest that if you are affraid of particle poisoning from the sedement then, order several 50ml sterile vials from a kit supplier. Then get to more syringe filters. (one rated.45 microns one rated .2) Then refilter what you have already cooked up and transfer to a new STERILE vial. This time use a small needle than the 18g monster provided in your kit. The 18g needles bore too big a hole in the stopper and this is what's causing your leaky vial. As for the color of the fina that you have you need not worry. After filtering you should be totally straight. Give yourself an injection and monitor the site. As others have said, BA kills everything, in the proper amount. No need for heat. Good luck hope this helps.
