Swimming pools blog

Hi all,
I have hundreds of tiny black bugs on the surface of my pool, half are
dead, half are alive. I have thousands of dead bugs on the floor of
my pool. They are tiny little bugs and if they bite they sting for a
second but thats it.
I called the company servicing the pool and this is what they told
me. Run the polaris extra hours to clean up the bottom. And buy a
solar fish. This will secrete an oil on the pool surface that will
clump up the little buggies so they all go into the skimmer.
What does everyone think, is this a good plan or does anyone have
other ideas? I have to get rid of these bugs, I am having 25 people
over on the 4th, any help is appreciated.
Thanks
Debbie
