Newbie - Stain removal via ascorbic acid

[herb396]

Janet,
I mentioned the chlorinating using calcium hypochlorite granular chlorine because it was what Ben's initial directions gave me when giving he help develop a plan to address the stain.

But if the calcium is going to be an issue,,,then obviously I just want to do the right thing.

I just went back and re-read the whole thread and realized that you have a plaster pool, not a vinyl one. In that case, cal-hypo is fine, because your target CH in a plaster pool should be 200-400 anyway. My mistake, sorry!!

In a plaster pool, calcium is a much bigger issue if it's low than if it's high, because if the water doesn't contain enough calcium, it will leach it from the plaster, making it brittle.

So you're right, Ben's right (of course), and I'll slink out of this now.....

I would follow Ben's directions. In fact, in this newsletter he talks about shocking with cal hypo in the skimmer

and he gives much fuller directiosn here:

He suggests that by using cal hypo this way excess calcium precipitates out in the filter and acts as a 'filter aid'. Worth trying but do keep tabs on your
CH and if it climbs beyond reasonable levels switch back to bleach.

It wasn't there when I started posting! We must have been posting at the same time. You just finished first because I was looking for Ben's threads with the cal hypo info.

I could not read the post, when trying I get a message "you do not have permission to access this page"...(looks like it would be good info) Anyway, I'll proceed by following Ben's direction, thanks for getting me back on track.

Thank you all for the guidance, can't tell you how valuable it has been for us.

If I am not mistaken, upgrading your membership subscription to Supporter will allow you acccess to those sections AND help keep this forum going. I believe it has already proved it's value to you! The Upgrade is well worth it!

Waterbear is correct. Upgrading to supporter will let you read those private sections of the forum with the Pool Letters in them. Full of good information.

Also, it is helpful to put all your pool specs in a signature line so that as we try and help, we can quickly see what your pool set up is without having to re-read long threads.
