What safety precautions are required when owning a swimming pool?

Clean the leaves and rubbish from the bottom, clean the filtration system, clean out the leaf baskets, Make sure there is sufficient water in the pool to cover the static skimmer.

All pools are different after standing for a period of time so at this point I would take a

sample of pool water in a clean bottle from about an arms length down from the surface and take it to a pool shop where it can be tested and advice given depending on the results.
