Proper pool maintenance and regular inspections will prevent any minor or major issues from showing up. For example, debris and leaves may leave the pool filtration and circulation system choked. Cleaning, brushing, scrubbing, and vacuuming the pool surfaces will keep them free from algae and stain build-up. Water chemistry balance is another thing.
Besides, investing in a stable pool fence, motion-detection in-pool alarms, and safety covers provide additional security for your loved ones.
