Heh... that's what it looks like when the GS leaks into the water. It's possible that you did not let the foam cure long enough before breaking the skin. When that happens, petroleum gets into the water and floats on the top. With agitation, this creates bubbles, like suds. It's somewhat difficult to remove it all, and I'm not sure if we've come up with the best way to do it yet. Draining the water only makes the oil stick to the sides as the water level drops, so that doesn't work all that well. Skimming is somewhat effective, but still doesn't quite do the trick. If you can get your arm into the tank enough, you might try removing the suds with a cup (hold it at an angle, letting the suction pull the bubbles and any floating oil you might see into the cup).
If it's not caused by the GS, the advice will still be similar, so that's a good way to start trying to get rid of the problem.
