yeah so my skimmer skims normally at night time
and when its day time, after i get back from school, its overflowing with water
then at night it skims normally

its like i have to open the water output to maximum in the day
and minimum at night

i sweearr my skimmer goes to sleep at night and wakes up in the morning

i have a PS75, besides telling me its a cheap piece, does anyone know why it does this?

runnin a fuge? ph swing comes to mind, maybe something to do with inherent surface tension orsum####

yepp. well a sump. got everything in tehre

and when my skimmer is going insane, if i unplug and plug back in
it goes back to normal
