This girl. I bought the jug from Leslies, brought it home and shook the h-e-l-l out of it. I put in a 5 gallon bucket with water and then stirred it even more. I then added it to my pool with pump running. I put water in the "empty" jug and shook that and did that until the water ran clear. Let the pump run for an hour. Went out to check and somehow the liquid crystallized I guess and now I have powdered CYA on the bottom of my pool. 

I have spent the last 1/2 hour brushing and brushing but all that seems to do is just move it from one spot on the bottom to the other. And we are having issue with a power due to a power outage so my pump kept shutting off and I eventually just had to shut it down so now I have no pump for a few hours.
How much damage am I doing to my liner?
