For background, my pool is fairly small in-ground and a pool service maintains it. I rent the house and the service people aren't exactly top-notch, so I am looking for advice so I know how to deal with them and the landlords.
Yesterday, we had some folks over for a pool party. The pump was running and the pool looked great. I checked the chemistry myself and everything was within ideal range according to my kit (tested pH, hardness, chlorine levels, alkalinity). A few hours later, the pump turned off (timer) and something disturbing happened:
1) The filter was making a loud knocking noise. For a while I thought it was a neighbor hammering or something so I ignored it. It sounded exactly like someone next door using loud tools.
2) At some point, a saw a cloud of particulates billowing from the skimmer return back into the pool.
I've attached two images showing the cloudiness in the skimmer and the cloud pouring back into the pool. When I noticed this, I turned the pump back on, which distributed the cloud, making the whole pool cloudy. Over time, it seemed to dissipate. When I turned off the pump again, the problem did not recur.
Anyone know what's going on here and what needs to be done?
Thanks!
