HIgh phosphates is the latest and greatest way to separate you from your wallet. There are very, very very few pools that can't be cleaned up with chlorine. Buying stuff from the pool store and throwing it into the pool hoping it will help is not going to get you anywhere, and is very much liable to increase your problems. You need to add chlorine, and maybe a little CYA. With CYA of 7 (don't know how they even measured that), the sun is eating your chlorine as soon as it goes into the water., I would add CYA through a tube sock hung in front of the return (target 20 ppm) but it takes several days for it to dissolve. Until then, you're going to have to make frequent chlorine additions to keep chlorine in your pool.
