Skimmer Belching White junk into my pool!

[Horizons]

Does it have a multi-port valve? You shouldn't be getting any flow back from your filter to your skimmer, flow should only be from skimmer to filter.

Perhaps your valve is going bad, but I'm having a hard time imagining this scenario. Is it coming from your skimmer, or return?

I THINK the filter is a DE type but I need to check this. The white cloudy stuff is coming out of the skimmer and not the return, no question about that.

I just thought of something else that may be a factor. Using the jacuzzi booster jets for more than 15 minutes causes the entire water contents in the jacuzzi to empty. I'm assuming that all this water is going through the filter and into the pool via the return. I then have to turn off the jacuzzi jets and turn on the filter to bring water back into the jacuzzi. Could this be related to my skimmer dumping white cloudy stuff into my pool?

Thanks for your help on this.
