de in pool?

there is a white slick emerging from our return extending to our skimmer. I'm guessing this is DE. Is the most likely cause a tear in the filter lining? Is this an easy home repair or do I need a pro?

thanks,

easy home repair.. the hard part is finding which grid is leaking .. they typically leak near the plastic nipple.

tnks, anyone have a pointer on how to accomplish this?

so I bought a book called something like the Ultimate Guide to Pool Maintenance and he has a pretty good discussion on how to clean the filter (interestingly, he doesn't believe much in backwashing).

Once I find the hole, are there kits to fix it? Or do I replace the entire element?

tia,

If it is a tear, a needle with fishing line and sew, sew, sew
