Cloudy Water After Alum

5. I talked with customer support at Natural Chemistry. Their "Metal Free" is just citric acid, so if there's chlorine in the pool, there's no citric acid left, since chlorine rapidly destroys citric acid.

Ben,
Unless the MSDS I have from natural Chemistry and the correspondence from them is wrong, Metal Free is basically EDTA (since they tout it as a 'phosphate free metal sequatrant). Their Stain Free product is ascorbic acid. I used to retail their products.
So much for their "customer support"!

I don't have Natural Chemistry MSDS sheets, for the most part; would you mind sending me copies of the ones you have, so I can add them to the SwimmingPoolResearch files?

Once I publish all that, we'll have better info on most of the pool chemicals, than the 'support staff' do!
