Vital statistics: FC 4.7, CC ?, pH 7.3, CH ? CYA >10
When opening the pool in late spring (middle of May) I shock the pool and then add some algicide. There is usually a fair amount of green algae. This year a day or so after I added the algicide I had foam covering almost the complete pool. The stuff is on top of the water so the filter cannot take it out. I am at a complete loss as to how get rid of the stuff. Can anyone help?
