I asked Marie (mbar) to take a look at this thread.
I just got metal magic myself, and have not had a chance to try it out yet. From what I understand, you will not have to use it after an initial dose, as metal magic is supposed to let the metal fall out into crystals so that it can be filtered out, or vacuumed to waste. Since you have metals only from adding them via your sanitizer, you won't be getting any more in your water since you discontinued it's use. Therefore, I would add borax to get your ph up to 7.2, then add baking soda to get your alkalinity up to 80 - 120. The baking soda should also raise your ph, so it should get to the right number 7.4-7.6. Your chlorine is fine a 3ppms, as long as you don't have any algae.
The reason your ph and alk went so low is from the metal magic - it gets rid of metals and staining by making the pool water acidic so it lifts off any stain so it can get rid of the metals. (hopefully it does!). So now you just have to get the ph and alk back in balance. Then you should be fine - just stick to the BBB. You shouldn't have to worry about adding any sequesterant after this
Thank you to all of you who offered your advise. This forum has been a blessing. Thanks again! Michelle
