Did you have a GWA problem? Yes, it will run for days with clean water, but the GWA rapidly clogs the DE. There is no way to bump the filter either, although I suppose you could let some water out of the cannister and shake it.
Anyway, that was the result of my tests. The GWA clogged the Magnum 350 in a few minutes. We're talking real pea soup here. I couldn't see the back of the tank. I used a UV sterilizer to get rid of it. That did work, and it did not come back.
