Hello pool experts! I installed a cheap Amazon PVC pipe fountain on one of my return jets today to help cool the pool off at night. It was on for a couple of hours today while the kids swam. I went out to see if I needed to adjust the fountain angles since the kids might have messed with it and I noticed the pump started up differently this time. It seemed like it took a while for me to see water coming out of the return jets and when it did it there were a lot of bubbles. Trying to make sense of it with my limited pool knowledge and make sure the fountain isn't messing up my pool/pump. When the pump is off and not shooting water out of the fountain, the fountain causes air to enter the jet line and pump right? So maybe it took longer to start up again because it had to purge the air out and that would be why there was extra bubbles?
Does that make sense? If that was mostly correct, is that causing any harm to my pump or other pool equipment?
Thanks for the help.
