Hi,
When I did my conversion a few yaers ago with a DE filter I ended up taking the filter apart and cleaning it every day for the first couple of days. It was so bad that I could not leave the filter on over night because it would plug so quickly. Be assured that after a couple of days it will not be so bad. While I was using baq I would use 50 to 100 lbs of de a year. Now I use less than 12 lbs a year. and that is because I like to clean the filter every now and then. I could probably just let it go and would have no problem. Stay the course and you will be fine. Change the de often at first baq really gums it up.
