I am a first time home owner which came with a pool. I opened my pool 2 days ago and I had to top off the water up to the skimmer. Today, the pool guy came, after the water was topped, and started the pump and vacuumed again and set up everything the left. Hour later, from the edge of the border, water started to come out!!!! Along with sand and foam!!!! I don't know what's happening and I'm freaking out. I have a mini pump which I used to drain out the wAter. Now, it looks like it stopped but I need to know what just happened. I didn't notice the water level go down, so I'm not sure if my pool has a leak. There was ALOT!!!! Of water coming out and foam. Please see the pic in the link. It doesn't have much water because I drained a lot, but you can see sand and foam. Please help!!
