Hi all, I just left "the dark side" of going to the pool store to get straight answers after finding TFP.
Here is my issue, I believe my pool has Mustard Algae. I attached a couple of pics so that you can see where I am right now.
The algae began to appear quite a while back only as a yellow cloud when I would brush.
I used something the store sold me to get rid of it and that seemed to work, but over the last several months I have begun to see the green/brown color on my steps and walls of the pool.
After searching online I found TFP and began SLAMing my pool on Monday (8/22) and raised my FC levels to 21 (I used the iphone poolschool app and it showed to shock at FC 21 for a CYA of 70)
Here were my test numbers on Sunday before I started SLAMing:
I check my FC levels twice a day (morning & night) and shocked to keep around 25.
I have not finished SLAMing because my FC levels have dropped overnight between 2-3 each night.
First question is should I be shocking at 10.5, 27.5 or 40.5 during SLAMing?
Second, when is it recommended to shock at the maximum mustard algae level of 40.5?
Lastly, I am running my pump 24/7 but have turned off my SWG, is that the correct procedure?
Thanks in advance for any help!
