First off, thanks for the TFP. I've had my pool for about ten years and learn something new every year. With TFP, I've already learned 3 new things in 3 days.
Now, for my question. I have low Ca hardness to the tune of about 150. I have metal stains (most likely manganese). And I want to try the borate procedure.
My current plan is to take care of the Ca issue first with calcium chloride (Peladow), then take care of the stains with citric acid, and then use borax plus acid (or just boric acid) for the borates trial. Is this the best order in which to proceed?
Also, should I bypass the heater when using the citric acid? I remember it was a step in the old Jack's magic stain removal instructions.
