My pool pump broke a while ago which caused my pools condition to take a dive. I replaced the pool pump and tried to restore it's health, but I still have one issue. As you can see here http://imgur.com/a/XBaAe , There is a residue that I am unable to remove from the pool surface. I have tried scrubbing to no avail. What would I need to do to remove this? Thanks for any help.
My pool levels from are available from the imgur link above.
