It is necessary for pool owners to make sure their pool is clean. One should try to handle any issues that arise as they're noticed, such as cleaning anything that looks dirty or repairing anything that does not work right. You should also be sure the pool is vacuumed, that the skimmers, pumps and tiles are clean.
Whenever possible, it is best to clean skimmers on a daily basis. If there are not many trees near your pool, you might be able to just use the skimmers to clean it a few times per week. But if you fail to clean the skimmers, you will notice very quickly that backwash occurs in your pool more frequently. Plus, your skimmers and the pipes leading to the pump can become clogged with leaves, hair and other substances, and this can cause your filtration system to stop working.
It is advisable to vacuum the pool on a weekly basis. While there are those who advise cleaning two times weekly, this translates into a lot of labor. When pools are located near shade trees or lakes, it might be necessary to clean more often. When you vacuum, it gets rid of foliage and various debris that compromise the water's pH balance.
A couple times during each swimming season, you should clean the pool pumps completely. This means really opening the pumps in order to perform the cleaning. A backwash may be performed according to the pressure listed on the pump equipment. When the pressure rises into the 40s, you will need to backwash as soon as you can.
It is essential to keep your pool clean in order to prevent the formation of algae, maintain consistent filtration and keep your pool looking its best. These are just recommendations, but if we are talking about pools, there is no such thing as 'too clean'.
