I added some more ascorbic acid, and some more sequesterer. It seems to help, or maybe it is just my eyes. But I get the impression from comments it should be instantaneous.... I'll know better as the sun gets lower, with no shade in the yard, it is just glaring right now and hard to see the bottom of the pool.

You mention to just circulate, but not filter the water. My plumbing is such that it always runs through the filter. Is this unusual? I have a cartridge filter, so I guess I could take the filters out??

I'll keep it running, and see how it goes.

Thanks for your help.

David.
