2 days? First timers should wait 7 days, or perhaps a
lot longer if you have green soup now. I'd pull the
batting out since it's only going to clog (way too small
-- you said 5-gallon bucket?). And you're sure that the
UV lamp is on...(never look directly at the lamp -- use
a mirror, else you WILL turn to stone). This is presuming
that you are pumping all water through the UV, and not
bypassing. It can take a couple of weeks or more for all
the full effect. When you noice that you've got less
green hairs (goop if you dump it) in your pump basket
(or whatever first-stage filter you have), that's when
it's going good. The water may be clear(er), but until
there's actually less goop collected, it's still not all
the way there.
