| I don't run a bead filter, but used one in the past in other application. They can do a wonderful job, but are not suitable to my present needs. My major objections are:
#1 They are energy hogs. They generate some back-pressure which must be overcome with horsepower. This relates to what bil calls their "compressive" mode of action. Being poor and living in an area with very high energy costs, this is a concern.
#2 They are pressurized housings and it is difficult to inspect the media. It's a lot of effort to find out if you have any persistent clumping and to correct the problem. I like to be able to see what is going on.
#3 They demand very regular maintenance. If you do not stay on schedule, they can be literal time bombs. I am easily distracted and not conscientious enough to effectively operate a bead filter.
#4 It is a lot of effort to build one as a DIY project. Like I said, I'm poor.
