I've had a lot of people asking me about this filter setup. The filter cannister is an FSI X100, and I'm using PONG 3 micron filter bags in it. I bought the cannister for something like $230 and the filter bags for about $3 from Control Factors in Gresham, OR. I'm not affiliated with them in any way, but I really want to give them a plug. These guys were quite intrigued with what I was doing. Filteration is their business, and they really know filteration. They took some time to teach me a little about the ins and outs of filteration, took a look at what I needed, and came up with this recommendation. I whole-heartedly recommend them (and they ship to anywhere in the country).
