We have inherited a new liner. Over the past week we have noticed some dark marks that were not here before. The vacumn is on everyday. Is there any way to prevent these marks or is there any chemical that will removed them. We have tried removing them but have had no success.

Have a read through HERE, evrything about pools.

Many thanks for your advice. This web site is definitely worth reading. I hope I can solve my problem and get rid of these marks.

Thank You. I have looked on the website and it well worth reading. I would advise anyone with a pool to have a read. Thank you for your reply it was a great help. I hope I can remove the marks with this advice.

No problem, I have used it myself many times. ;-))

It depends on what the marks are composed of, it could be a metal plating out, it could be a stain from oxidising leaves or metal, or a host of other reasons. What size pool do you have and what is the sanatization regime?

If you want to get in touch and first send me pics of the stain then I can start to help you to get rid of it.

I suggest that you email me your address with some pics and phone number and we'll start from there.
