Hello!

I'm still very new to this; this is my second time posting. It was recommended that I try to SLAM my pool due to it constantly turning green when adding chlorine and high CC. I've been performing the SLAM for a few weeks now and the pool has cleared to a light green color. I haven't passed the overnight test yet so I'm not going to stop the process but I'm concerned about the brown staining and green color the pool has. The pool has had this staining since I started the SLAM process. I've gone through 22 gallons of LC (12 gallons of 10% and 10 gallons of 12.5%) so far. I run the filter 24/7 and brush it multiple times a day in addition to having the robot running 24/7. I realize I need to continue to be patient I'm just concerned with the staining; Vitamin C or Absorbic Acid does clear up the staining and get the water clear but it does return; I did it when starting the SLAM but days later it was back to green. I've removed and re-added water a few times during the SLAM process due to heavy rains.

Current Test results:
FC 16
CC 1
pH 7.5 - it was 7.2 when I started SLAM
TA 110
CH 125
CYA ~35-40 - Using 40 to SLAM


Questions:

Will this staining cause damage?

Should I clear up the pool with Vitamin C and just wait till I clear the 2 tests of SLAM (CC & OCLT)?

Do I just wait to clear all the SLAM tests? Will I even be able to clear all 3 tests? The water is clear but will the green go away?

Is there something else I can/should do?


Thank you!
