Hi and Welcome to TFP! Lets see what is going on with your pool. Have to ask a couple of questions first to see what is going on and what this is.

Can you get any of it out? You can use a turkey baster to suck some up. Then you squirt it out onto a white paper towel laid in the strainer or such to let the water pass through.

What have you added to your pool as of late? Do you have a pool service? Do you have a test kit of your own?
