ascorbic acid treatment for my pool?

[masspool]

Thanks for the good advice, mbar !!

My Pool looks great!

The PH is 7.2 and am slowly adding bleach ... it sure seems to be eating the bleach because I am not getting a reading yet (FC is still < 0.5). I will keep adding bleach, a little at a time, until chlorine gets to an acceptable level.

I was running my pool at a fairly high PH (7.6-7.7) level and high chlorine level for awhile so I think that this may have caused the metal staining to increase. I am also told (by the local Pool store) that the town water does this to local pools.

Anyway, it is nice that this treatment works on the problem. I wonder if I should use Metal Free regularly to prevent this? The stuff is expensive ($20 a liter).

Draining is not an option here - ground water level could pop the pool and we are in water coneservation mode.

Thanks Again - This website is very valuable to pool owners!!
