I think its a pine tree thanks for your reply and I may try an organic killer

Be careful what you put in your pool. I'm not sure what you mean by "organic killer".

The problem with pine sap is that the stuff that would really remove it would be a solvent or an oil . . . and you definitely can't put those in your pool. You could call Natural Chemistry and see if one of their enzyme products would help; they advertise cleaning up motor oil, so one of their products might help with pine rosin. If you go to the link below, they have a live chat option. Do NOT buy their products willy-nilly; they have some that are worthless or worse.
