Good evening TFP,
I just got my first house last month and it came with a ~7200-7500 gallon inground pool. It was pretty green when I first got it and I worked on it here and there until we moved in a few weeks ago. I have been shocking and brushing what I assume to be black algae for a while now, but not SLAMing with any actual accuracy since I just got my FAS DPD test today in the mail. I attached some pictures of the worst spots still- they are all on the deep side of the pool especially near the one step we have there. Since I can finally see the main drain now I do also notice some staining. I will put a picture of that out of curiosity at the risk of going off-topic.
The pool had black algae around all the edges of the walls and it was much worse before these pictures. Kind of curious on how long to expect before realizing I am messing up or something else is afoot. I was a bit curious about if I should be draining throughout the SLAM process as well. My CYA is unfortunately around 70 but I don't have much in the way of draining besides the bib that's attached to my cartridge filter so its a very slow process and one I want to be careful about. Not sure if I am really supposed to be draining from there.
