Being able to find neither of the recommended sequestriants in town (Jack's Pink Stuff or Metal Magic) I ordered some online. My Ascorbic Acid will be here today and I haven't heard where my Jack's currently is. I'm a very impatient person and want to start the treatment ASAP, but don't want to start without it.
As I was walking through Walmart to buy a nice, large measuring cup for chemicals I happened on the pool section so I stopped in to see if they had calcium (they didn't) but I did see they had HTH Metal Control. It's Hydroxyethylidene Diphosphonic Acid and it only about $16/quart. Has anyone got an opinion about it? It would be nice to not have to buy from online if I need some quickly.
