Brown Sludge Well Water - White Socks and Vitamin C is the answer!

It's called EcoOne Pre-filter and it claims to dissolve heavy Metals, Lime, Scale, Organic Contaminants among other things. . . . . Big waste of money for me.

I've pretty well concluded that ANY swimming pool product with the letters "Eco" in the name is a rip-off! There might be a few exceptions, but they aren't coming to mind at the moment.

Hi All, I found a bulk, powdered, Vitamin C (Vitamin C Ascorbic Acid Powder). I will be switching to this from the tablets when the tablets are all gone. The bulk powder won't have the additives they use to make the tablets. Also, I can measure the amount I want to add easier.

This is a 5 pound container on Amazon for $27.91 on 6/4/2012. Shipping to me in North Carolina was only $2.49. Less than the cost of gas round trip to town.

Hi SMC;

The only problem with your "Ascorbic Acid" (vitamin C) is that it's "Citric Acid" (lemon juice acid)!

You can use citric acid for metal clean up; some pool chemical companies sell it for that purpose. But, it's not as effective as ascorbic acid. However, with the larger dose it may well work very well for you. Keep in mind that neither citric or ascorbic acid are chlorine compatible -- chlorine rapidly destroys both. Also, the by-products formed when chlorine breaks down citric acid are better not breathed -- so don't swim once you begin re-chlorinating, till you've held a chlorine residual for a few hours.

And . . . if you'll use polyquat while your are using the citric, you won't have to worry about the pool getting algae. Polyquat is compatible with BOTH chlorine and citric acid, so you can begin adding it while you are letting your chlorine levels drop.

Thanks so much for clarifying the difference between Ascorbic Acid and Citric Acid. This has all been so confusing and stressful. I really appreciate your tips and cautions about combining Citric or Ascorbic Acid with Chlorine. I did additional research after your reply and found this Ascorbic Acid, Vitamin C Powder - 11 pounds for $59.99 with shipping to me in North Carolina of just $1.89. That's just $5.63/pound.
