I'd like to thank cadman and his tutorial. I just got back from the hardware store from getting rubber bumpers for the bottom of the plexiglass. While I was there I picked up some paper bags for filters. I got several different sizes: 1/2,1,3,5, and 10. I have other different filters I am going to try. I will report my findings. Can't wait to this thing is set and ready to use. Tried to post a pic, but it was too big
