Hello all! Long time lurker, first time poster.
I woke up last week after a bad thunderstorm left a branch in our pool. I removed it, vacuumed, brushed, etc. That day I noticed my FC was at 1.
I've since brought my FC up to 25 (with bleach). My problem is that my water is a very light green color.
I was reading about mustard algae and how it grows on the sides and in the shade. In my pool there is some dust looking stuff on the bottom. It brushes off relatively easy and it kicks up dust and clouds up the pool.
My question is if you guys think it's mustard algae, pollen, or something else.
TA: 250 (I know this is high, but the pool was fine before)
Any advice is appreciated. I haven't tried the overnight chlorine test due to me not having a high end kit. I've been using the dilution method to get a best guess of my FC, which has been about 25-30.
