I have an 18' above ground pool. We didn't put a cover over it this winter so it got full of leaves. I worked for several days, got all the leaves out, got the chemistry right, etc. but I noticed after scooping the leaves out, where I was dumping them, this white powder residue. I'm not sure what it is, but I believe its the reason I cant get my water clear.
My chlorine is 2.5, PH is 7. I've only got a small test kit that test those two. I plan on getting a better one this weekend. Any thoughts on what this might be or how to clean my water up would be greatly appreciated.
Here are some pics of the residue and of the water.
