I did full test on the pool. Honestly not sure what I should do next, so awaiting replies.
First cleaned my pump basket, backwashed filter for 2 minutes (yucky looking color then clear), and did the rinse setting for 20 seconds.
First did the chlorine test with the OTO test and it was barely registering faint yellow.
Confirmed with the powder test.
FC: 0.5
CC: 2.5
PH: Under 6.8, very faint.
Alk: 50
CYA: Just at 20 when the dot disappeared. I was turned away from sun, looking into tube at waist-level in my shadow.
Here are some pics. Just comparing to a few days ago, it looks worse. I don't know how well you can make up the orangey color under the waterline, You can see all the dead algae on the steps.
To be clear, I added 12 gallons of 6% bleach to the pool last night (from 8pm-12am). We also did the PH up a few days ago, so not sure why that hasn't come up? The CYA I added stayed.
