I've read that unlike "regular" algae, mustard algae is "easily brushed away", but how easily? Is it still attached to the surface?
I've got a fine layer of dust covering my entire pool every morning and I've been keeping the chlorine levels high (around 12 ppm), with no combined chlorine. This stuff doesn't even need to be touched to be removed. Even just moving your hand over the area is enough to blow it out of the way. Here's a short video.
As you can see, it's just sitting on the surface. Anywhere the barracuda vacuum goes leaves a perfectly clean area as well. Is this indicative of mustard algae or is it likely to be something else? It's got a yellow appearance to it, but the high chlorine and no CC leads me to believe it's probably not algae.
I've noticed that my return valves pump out a brownish slurry everytime it's been off for a while, making the water cloudy. I'm assuming this is something my sand filter is not capable of filtering.
My next step today was to try adding a bit of DE to the filter using the guide found on this site.
Any other advice?
