water level in skimmer basket drops when pump is running

I went to run the polaris today and i noticed a lot of air coming out of my return jets. i figured out that the water level in the skimmer closest to the pump was dropping very low and letting a ton of air in. there was also a strange white cloud of something coming out of the wall connection for the polaris. if I turn the pump off, the water level returns to normal. the skimmer farthest away is barely doing anything (it's always been weaker) any ideas where to start looking? right now only the bottom drain is on. thanks!

It is almost impossible for the pump to suck more water out of the skimmer than can "fall in" from the pool.. Only two things can cause it.. Either your water level is too low or your weir door is stuck up.
