Pool boy blues

So the water in my pool has turned green. It's disgusting. I have never had a pool before. I didn't realize you have to be a chemist to maintain it. In the last two years, I have purchased enough chemicals to outfit a high school lab, I'm sure. But over time, I got into a regular maintenance program that kept the water clear, bright and sparkling. Of course, this is the rainy season and God knows what is being introduced into the mix when we get a significant rain. So I am playing chemist and doing the best job I can to fix the problem. The pool has a paper filter system so I can change filters frequently. I bought a new broom to dedicate to the pool and I use it to stir up any algae or sediment that settles around the perimeter after I have vacuumed. In theory, the chemicals kill algae and fix particles to themselves to be trapped by the filter. Hmmmm...we'll see. I have done this successfully in the past but I can't remember if it was rainy season or not. Then again, I can always call the pool maintenance company. They'll probably straighten it out in an hour or so.
