Re: Heavily stained fg pool with red/rust scale? (pics attac

It's quite common for the pool to cloud up after the AA treatment. Also, you're not using one of the recommended sequestrants. You need to find one based on phosphonic acid or a derivative thereof. There's a list of the ones we recommend in Pool School.
You need to slow down a bit and let us know what you're doing each step so we can keep up and help you. Since you overshot the TA so much, the pH will naturally rise and you can adjust it back down to 7.2 whenever it gets to about 7.8.
When you say the pool has a green tinge to it, do you mean the water is green tinted? If os it's probably the metals and not algae. You said you put Polyquat 60 in it, so if you put the recommended amount you should be fine.
Post what the problem is today and a timeline of everything you've done up to now. so I can catch up.
Thank you so much for taking a look at this! The following timeline is post shock process and passing the overnight FC loss test. The pool was clear and balanced before I began the AA treatment.
Here is the timeline for the AA treatment:
June 1 or 2 I had a clear and balanced pool but it still had massive staining everywhere.
I started to allow the chlorine to drop-which didn't take long because we had quite a bit of rain.
June 7 my tf-100 arrived. I brushed and vac'd to waste and got the pool a lot cleaner. I cleaned the cartridges, reassembled everything and replaced the lost water. Then I tested. Here were my results:
FC 0
pH 7.8
TA 210
I used the pool calculator to determine how much muriatic acid to add to lower the pH. I put in the exact amount prescribed, but the pH dropped to 6.8. Then I had to raise the pH using borax. Once I got it back to 7.2, I started the AA treatment. I put in 32 oz of a polyquat 60 algaecide. Then I put in stain free going around the pool slowly (expecting the magic stain lift) and nothing happened. I brushed and brushed. Thirty minutes later when I saw no change, I added another bottle of stain free (3.5# total). I did see a wee bit of change but only in the place where I stopped and poured about 8 oz of acid in one spot. Then I brushed again hoping that the stain free would spread through the pool and and lift the stains. I added 32 oz of Sequa sol to capture the metals.
I had read in this thread:
major-iron-stains-need-any-advice-you-can-give-t20475.html?hilit=sequa%20sol that sequa-sol was one of the three recommended. My local store did not have Jack's so I got the sequa sol. I guessed I messed up on that one.
June 8 The pool was cloudy-which I wasn't surprised by because I read that was pretty normal when doing the AA treatment.
June 9 The pool had become very cloudy. The water turned a whiteish/opaque color. My pressure did not raise, so I didn't clean the cartridges. I had cleaned them very well just a few days earlier.
June 10 The pool water was taking on a green tinge. I got more polyquat 60, sequa-sol, and got 2# of ascorbic acid (instead of the citric acid). The water tested at:
FC 0
pH 7.5
TA 210
There were suspended particles in the sample I took. I didn't know if that was a good thing or not. The ozonator has been running all this time. Also, I have not turned the pump off, so it has been on 24 hours a day since I began the treatment on June 7.
June 11 The pool is greener and still cloudy. I have attached a picture from this morning below. I am hoping that I don't need to raise the chlorine and start over because I don't want what little lifting I have had to re-attach. I don't know what to do.
What do you guys recommend I do?
