Do you know what your calcium hardness levels were, before you started this process? What are they, now?

Re: Results of Ascorbic Acid Treatment for Stains
80 before procedure and 80 now. Never could get sample to turn red - only purple. Took 8 drops to get it to turn blue.

Re: Results of Ascorbic Acid Treatment for Stains
Video was on testing TA. I have no issues with TA test and as of a few days ago it was 60. I have not tried to move it up much for fear of moving PH up from 7.0 while trying to get chlorine up and water balanced. The calcium hardness test was the one in which I could not get to turn red ( kit says it will turn red if calcium hardness present) after adding the 5 drops of R0011. The 80/80 represents the calcium hardness - 8 drops of R0012 to turn sample from purple to blue.

Re: Results of Ascorbic Acid Treatment for Stains
Sorry; watch the CH interferences video.
I'm running into a sort of Catch-22 situation with HEDP and calcium. HEDP also can bind with calcium, and become unavailable for other 'work'. But you can't just increase the HEDP dose, since high enough levels will precipitate colloidal calcium phosphonate that is very difficult to filter.
We need to know what your CH levels are.
Re: Results of Ascorbic Acid Treatment for Stains
CH is 90
I cannot get to minimum FC level of 3.0 without stains returning. I added the HEDP each time stains began to return (2.5 qts), but no help. So I sprinkle a few ounces (by volume) of ascorbic acid to keep them from getting too bad. Since the second attempt at the stains began on July 31, I have used 12 qts of HEDP ( Kem Tek or Jacks Pink Stuff), and 18 gallons of bleach. I have added bleach slowly with no one time add exceeding 1 gallon (only when FC=0). Most bleach additions are 1/2 gallon a day or two times per day. Water is clear - cloudiness cleared up within 4 days or so. Stains come back every 3-4 days as FC approached 3.0 or higher. HEDP is not cheap at quantities I am have used - need to try something different- maybe some fill dirt and a dump truck.......LOL!!

Yeah, I probably spent $500+ when dealing with my stain problem.
