Can someone tell me if this is Mustard Algae?
I started a Slam on Sunday to treat an outbreak that formed while I was away last week. Once I got the water clear enough to see the bottom (Tuesday morning), I started seeing a few small spots like these (not on the walls just on the bottom) so I vacuumed the spots to waste and raised my chlorine levels to 26ppm with CYA at 30. Chlorine reading after dark was 24ppm and dropped to 22ppm overnight (Wednesday morning).
Because of other pressing matters, I had to suspend my slam on Wednesday (today). When I got back to the pool today the water was still a little hazy and three of the pictured blooms appeared.
Was wondering what my next steps should be. Slam at regular levels or Mustard Algae chlorine levels?
Here are my current readings:
FC:8
CC:0
CYA:30
PH:7.6
TA:100
CH:120
Some of my reagents are a few months past expiration. Would this throw my readings off by a lot? Ordering a new kit today.
Thanks in advance for any help!
Also, my pool store said that my CYA reading may not be very accurate because my phosphates are very high (1456). They said my CYA was 44 when my readings showed less than 30 - probably closer to 20 but maybe because old old reagent. Should I be worried about my phosphate? Seems like most here say not to worry about it.
