We can help you with that little green problem when you're ready....Can I suggest you start here?- ABCs of Pool Water Chemistry then delve in to the other pool school articles.
In addition to reading the ABC's article, you will need one of the Recommended Test Kits to properly manage your pool. I use the TF-100 because it's the best value and they have a freshness guarantee. You can order it here: TFTestkits.net. They ship fast - you should have it in your hands in 2-3 days with normal shipping. If you want to really do the right thing, I would order one of these test kits tonight. Do not rely on pool store testing - it is notably inaccurate and they will use those results to sell you all sorts of chemicals you do not need that will cost you way more than this test kit.
