Swimming pool circulation systems should be adjusted to remove:

100% from the bottom
25% from the surface
50% from the bottom
75% from the surface

The correct answer is: 75% from the surface

Swimming pool circulation systems are designed to remove debris and contaminants from the water, ensuring a safe and clean swimming environment. While option D - removing 75% from the surface - may seem counterintuitive, it is actually the most effective way to remove debris. This is because debris and contaminants tend to float on the surface of the water, making it easier for the circulation system to capture and remove them. Removing 100% from the bottom (option A) or 50% from the bottom (option C) may not be as effective as it only targets the bottom of the pool. Similarly, removing 25% from the surface (option B) may not be enough to fully capture all the debris and contaminants in the pool.
