    Phosphate does not consume FC...algae does.

    How are you shocking? What is your target shock FC? What are your numbers, including CYA? How are you chlorinating?

    Re: high phosphate levels

    Phosphates won't cause your FC to go to zero. If you keep your FC level high enough for your CYA level (see chlorine/CYA chart) you can ignore phosphates.

    What have you been shocking with?

    You need to read Pool School on how to shock. You also should order a good test kit if you don't already have one. It will allow you to take control of your pool and things will go much better once you know the real numbers.
