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!!

Yes, you can use Metal Free on a regular basis, also there are Sequasol, Jack's Magic and Metal Magic sequestering agents that are very good. You can add this whenever you add a lot of water to the pool. My advice is to keep an eye on the pool, and when you see stain start to form, take the ph back to 7.0 and add sequestering agent. This should lift any new stains. Keep in mind that sequestering agents get eaten up over time too.

Glad to hear your pool is stain free - enjoy. Just remember you can always add a small amount of ascorbic acid if you see a lot of stain starting and put the filter on recirculate. Wait till all of the stain is gone, add sequestering agent, and then put it back on filter. This will get rid of the stains without using a lot of ascorbic, so it is easier to rebalance the water.
