Ben,
I appreciate the guidance, feels like I've been at a total loss with no plan. I have a few questions:

1. Carefully lower your pH to 6.4 - 6.8. (what do I do to lower the pH?) then add a little more acid (meaning the same ascorbic acid ?) (how much is a little?) Keep it there for several weeks. In essence, you are doing a very, very mild acid wash, among other things.

2. Use twice weekly doses of polyquat 60 to allow you to run low levels of chlorine without getting a pool full of algae. (understood)

3. Maintain low chlorine levels between 0.5 and 2 ppm. (is the pool swimmable during this time?)

4. Add 1 1/2 times the maximum dose on Metal Magnet or a similar liquid metal control agent. Be sure to allow for any prior use in the past 2 weeks: deduct that from what you add. (would Pool Stain Treat by United Chemicals be an equivalent?)

5. Brush the pool a lot, especially starting a day after you get the chems in line. (understood)


Chlorinate by putting trichlor tabs (never heard of these, where can I get them?)

Thanks for the help !
