Marie -

I have been following all of these threads with high interest and was wondering if you have summarized the process for removing the stains (the full treatment). I have stains on my plaster pool which I have been battling with Jacks blue magic but since I have an SWG I have a rather high PH and I typically keep the FC at 3-5ppm. Based on all the threads I am still a little confused on exactly what steps to take to get rid of these nasties. LEt me take a shot at this and let me know how close I am -

1) Bring PH down to 7.0-7.2 --> Muriatic acid
2) Reduce chlorine as much as possible as it will eat up the absorbic acid
3) Add absorbic acid to remove the stains and filter?
- How much #'s per 10,000 gallons?
- Filter or not? How long?
4) Keep adding muriatic acid to keep the PH down and do not add any more chlorine
5) When do I add the sequestor? When the stains dissappear or before? --> sounds like ProTeam Magic is the stuff to add.
6) I have a DE filter, I assume that as the ProTeam Magic causes the metals to fall out, I should vacuum them and then backwash my filter.
7) Once all stains are gone then add bleach slowly to raise the CHlorine backup. Keep the PH around 7.2- 7.4. Also check the Calcium level as some of it may have precipated out, correct?


Does that sound correct? Please let me know if I got the gist of this, I will probably take a stab at doing this next week.

Thanks much
John
