Treating iron stains-
Just opened pool it has zero chlorine per our guy. According to the AA TREATMENT I should add and metal free algeacide first ( but how much 20k pool) there is no visible algae. Then I ad up to 2 pounds OF AA followed by a flockulant ( how much) run pump without cartridge 24 hours and slowly bring up chlorine and keep ph under 7.2
 
Print the instructions out. Follow them exactly.
There is no mention of flocculant. Sequestrant and Floc are not the same.
There is a link in the article to the sequestrant you need.
You should add according to the label. A bit more than label is ok.

The top sequestrants are:

  • ProTeam's Metal Magic
  • Jack's Magic The Pink Stuff (regular)
  • The Blue Stuff (fresh plaster)
  • The Purple Stuff (salt)

Sorry, I had hand surgery and voice to text is not working. My question is I added the algicide? I am on my way to get the sequestrant. I will put in the Ekic acid, but then can I immediately put in the sequestrant after that I should let it run for 24 hours and then vacuum the pool to waste and then slowly bring up the pH and chlorine.

Before AA Treatment
  1. Take your chlorine down to 0 and PH down to 7.2; if there is chlorine in the water, it won't hurt; it will just eat up the ascorbic acid, so you will need more to get rid of the stains. Let it decline naturally. Remove tablets, stop adding liquid chlorine, or turn off the SWG.
  2. You can add Polyquat 60 per directions on the bottle to avoid getting algae while the chlorine is low.
  3. You will need about a half to one pound of ascorbic acid per 10,000 gal. Go lighter on it and see if all the stains lift off before adding more.
  4. Put the filter on RECIRCULATE if you have a Multi-Purpose Valve(MPV) on your filter. If you have a cartridge filter, then remove the cartridges.
  5. Use a cup, go around the pool's perimeter, and drop it down the sides.
  6. Let the ascorbic acid circulate for 1/2 hour. You will be amazed how the stain disappears before your eyes.
  7. If the stain is not all gone, leave the filter in CIRCULATE and add more ascorbic acid close to where you still see the stain.
  8. Leave it in CIRCULATE until all of the stain is gone. (add more ascorbic acid if it circulates for 1/2 hour and there are still stains)
  9. When the stain is gone, add enough sequestering agent for the volume of your pool - more is better than not enough.
  10. Put the filter back on FILTER if you changed it on your MPV, or replace your filter cartridges and leave it on 24/7.
The ascorbic acid will bring your ph down, and sometimes the alkalinity.

After 24 hours, you can start to rebalance the water.

After AA Treatment
  • Bring up your pH and alkalinity - use Arm and Hammer Washing Soda first; it will raise both pH and alkalinity.
  • Make sure you test in between because you don't want your pH to exceed 7.2.
  • If your alkalinity is in range, and you still need to raise your pH, use Borax to take it up to no higher than 7.2.
  • You can start to bring up your chlorine. You want to do this slowly. It will take a lot of chlorine - preferably using liquid chlorine only at this time, and try to take it up to your minimum chlorine for your cya according to the Chlorine/CYA Chart.
  • As you slowly raise the chlorine, watch for stains starting to form.
  • If you see stains, ensure the pH is no higher than 7.2, and add more sequestering agent. You should see the stain lift in a couple of hours.
  • Do not raise to SLAM FC levels! Do not do a SLAM for at least 2 weeks!
  • Make sure you keep your pH low (7.2) for a week or two - it won't be hard because the ascorbic acid and sequestering agent will help it stay low.
  • Once your chlorine starts to hold, it means that you have used up the ascorbic acid in the water, and it will be easy to rebalance the pool back to recommended levels.
Here are two important notes:

  • High pH and chlorine will precipitate metals not sequestered out of the water and onto the pool's surface again. If this happens, reduce the pH to 7 or 7.2 and add more sequestering agent. This should lift the stain off.
  • You can add Polyquat 60 to the water before starting the stain treatment to avoid getting algae while the chlorine is low.
 
OK, I got the sequestrant and everything seems to be going well. Stains seem to completely be gone. It has been six hours. I put my dolphin in to get the dirt off the bottom and we will be turning the pump on with the filter. It has been recirculating just the water so now I will put the filter in. Run pump 24/7 Tomorrow I will start to rebalance the water with baking soda and borax and then chlorine liquid and test frequently to keep ph at 7.2 or less and FC /cya balanced. I had a lot of trouble with CYA being very high last year based on Leslie‘s so I bought my own kit and got it down to 50. Our pool man did not want to drain the pool because we have a high water table and there is always water behind the liner unless we have a long dry spell, I spent most of last summer draining the water and refilling it even though I was told that it’s not the correct way to do it somehow over the three months it did seem to go down as long as the CYA is reasonable when I test it tomorrow, I think I will be in good shape getting the rest of the water balanced Thank you for your help. I struggle with this because my husband doesn’t trust. I know what I’m doing and wants to jump ahead and just dump the chlorine in so it has been a battle.
