So, I believe I have a bit of mustard algae in my pool. I'm preparing to SLAM.
Notably, this is a new pool to us, 20x40 vinyl. Fresh liner a month ago. Pool was filled with 30,000 gallons of lake water that I was trying to balance with test strips. Then I got smart and bought a TF100 kit.
Algae is more like clear, slimy patches and light tan powdery patches, mostly on seams. When I brush even the clear areas, a white powder floats around. Water is pretty darn clear in spite of this, until I brush.
Current values:
FC 2.5
CC 0
CYA 30
CH 300
pH 7.2
TA 140
I'm currently chlorinating with trichlor pucks, mostly because I have them and CYA was already low. I plan SLAMing with liquid. I see that I should SLAM to 12 ppm until complete, then to 19 for 24 hours.
Questions... screw with the ph/ta issue after slam or before?
This is mustard, right?
