Vacuuming of the pool bottom should be done:

before the pool is closed
after the pool is used
after foreign matter has settled
before testing water

The correct answer is: after foreign matter has settled

Vacuuming of the pool bottom should be done after foreign matter has settled. This process is typically done to remove debris and dirt from the bottom of the pool. Option A is incorrect because vacuuming before the pool is closed does not give enough time for foreign matter to settle. Option B is incorrect because vacuuming after the pool is used may remove newly settled debris. Option D is incorrect because testing the water should be done before vacuuming to ensure the pool chemicals are properly balanced. Therefore, the best time to vacuum the pool bottom is after foreign matter has settled to achieve the cleanest pool possible.
