OK, here is a weird one for you guys.... hope you can help me. I have a new pool - 35,000 gal, rough concrete waiting for tile to arrive. We're using the pool until the tile gets here. The chemistry is still out of whack, i.e the PH is 8.0, not enough CYA yet etc. But here is the weird thing...
I'm using powdered Trichlor, adding until my FC is about 7PPM at night, the sun cooks it off during the day until it is about 1-2PPM in the late afternoon then I repeat the process. I have very little to no CC and the water is crystal clear. BUT... it looks like spots of green algae are growing on the floor but I deduced that it only happens where I put the chlorine. I mix the Trichlor in a bucket of water then pour it into the pool. There is a bit of residual powder that doesn't get dissolved and it sits on the bottom - the next day, right where the powder was is a patch of what looks like green algae. It doesn't keep growing and it doesn't go away. Has anyone encountered this before? any help would be greatly appreciated.
Thanks
