Opened my pond...opps I mean pool and got it from green to clear with your help. Thank you, thank you, thank you! Now i have yellowish stains on my steps where the green water was all winter. My question is what can I safely use to clean it? My sister in law used a Magic Eraser cleaning pad made by Mr Clean and it worked great. With all the trouble I have had in the past I am scared to use it because, knowing my luck, it would add something to the water and cause problems. The only thing I have tried is a scrub brush w/o any cleaner and it didn't work.

Thanks,
Paige
