The frequency of water testing depends on several factors, including:

• Water temperature
• Pool size
• Number of swimmers
• Usage intensity

Warmer pools or those with higher usage require more frequent testing, while cooler pools with less activity can be tested less often.

Address any damage to your pool cover promptly to ensure its effectiveness. For holes up to 8 inches, use a pool cover patch, which is usually peel-and-stick and suitable for all cover types. For larger damages, especially on safety covers, consider professional repair. Taking quick action helps prevent minor issues from worsening and extends the lifespan of your cover.

The frequency of shocking your pool primarily depends on temperature and usage. Generally, pool owners should shock their pools weekly during the swimming season. Additional shocks may be necessary after heavy rain, high usage, or hot weather, as these conditions can deplete chlorine levels. 

To determine if shocking is needed, test your water and compare the Free Available Chlorine (FAC) and Total Available Chlorine (TAC) levels. If the difference exceeds 0.2 PPM, it’s likely time to shock. Always consult recommended water balance guidelines when testing.

The ideal cleaning schedule for your pool filter is not one-size-fits-all; it varies based on several factors:

• Frequency of pool usage
• Filter size
• Amount of debris entering the pool
• The presence of a suction-side pool cleaner

These factors influence how often you should clean your filter. Regardless of whether you have a sand, cartridge, or diatomaceous earth filter, a general rule is to clean it when the pressure gauge reads 8-10 PSI above the normal "clean" pressure. This helps maintain optimal filtration efficiency.

To clear cloudy or green pool water, start by addressing water balance and circulation issues. Steps to take include:

• Testing and balancing the water
• Shocking the pool if necessary
• Checking and cleaning the filter, pump, and skimmer baskets

The longevity of pool chemicals varies; dry chemicals typically last longer than liquids if stored properly. The ideal storage conditions are dark, dry, well-ventilated, and temperature-controlled (between 50-70°F). Extreme temperatures can render chemicals ineffective. Due to potential storage challenges and potency loss, many pool owners discard unused chemicals annually and restock each spring.
