My pool is surrounded by trees, and leaves and organics are constantly being blown into the water. I recently bought the home/pool and I'm new to pools maintenance and have a weekly pool guy, though I want to eventually take over. I am currently using this product to keep the algae away http://www.amazon.com/Natural-Chemistry ... +phos+free
Is this something I should plan on adding weekly forever? If I get good a better understanding of my pool chemistry and keep the levels good, would that take care of the algae on its own or will I always need an extra product like this since I have constant leaves in my pool?
