Just so you know, they do not run continuously... In-case you didn't...
They will remove certain spores of parasites from the water, but not disease as the pores are too big to filter out bacteria and viruses (is that even possible?). I know that ich spores, in the free floating stage (there are 3 stages) will be removed... Though I doubt that it would make much of an impact on the curing time because you can only run it so long...
