No, you can't run diatoms 24x7. The filter media get clogged very
quickly,
typically within a few hours. Diatom filters are used as occasional
water
polishing filters, not as permanent filters.

Maybe you can't, but I can.

If your tank is so dirty it clogs a diatom filter in under a week or two
you have bigger problems than trying to make it crystal clear. Try some
elbow
grease and big water changes.

Isn't a diatom filter the same thing as a diatomaceous earth filter? I have
one on my pool, and the only time it has lost effectiveness is after I
neglected the pool and let it go green. I did a massive chlorine shock to
the pool, and filter it like hell. The resulting algae gummed the filter up,
but a quick backwash fixed that.
