Pool Care Don’ts

While we generally guide pool owners toward solutions to their pool care woes, sometimes it’s best to learn from others’ mistakes to avoid making them yourself. Here are some things we DO NOT recommend.

Shocking

  • Don’t shock your pool during the day. Sunlight will burn off your unstable chlorine (aka shock), so it is vital to shock your pool during the night to ensure it has time to do the job properly.
  • Don’t add shock through your skimmer.  This mistake can be VERY dangerous because pool shock (calcium hypochlorite) and chlorine (DiChlor or TriChlor) will mix to create a deadly gas and can cause an explosion when mixed through your automatic chlorinator. This can not only cause bodily harm, but can also damage your pool liner, floor and walls.
  • Don’t add shock directly to your pool water. Dilute the shock in a bucket of warm warmer before adding it to your pool. Add shock to the water, not vice versa. The diluted solution will be safer to work with and will mix better with your pool water. It will also avoid shock settling on your pool floor and causing your lining to become frail, eventually leading to leaks.
  • Don’t swim right after shocking. Ensure chlorine and pH levels are in the proper range before swimming. If you want to be able to shock your pool and swim immediately, use a non-chlorine shock.

Brushing

  • Don’t forget your pool brush. Your pool vacuum is not a substitute for your pool brush. Be sure to brush the bottom and sides of your pool at least once a week, especially the hard to reach areas. Brushing is vital to removing bacteria, germs and algae, while the vacuum is great for the larger debris.

Vacuuming

  • Don’t use a robot on algae. If you have an algae problem on your hands, do not use an automatic cleaner to try to remove it. Manual cleaners are the way to go in this scenario because pressure-side automatic cleaners will push the algae up through the mesh bag, clog it and blow it around your pool.

Balancing

  • Don’t neglect pH and alkalinity. Maintaining the proper pH and alkalinity levels is necessary even if your pool water looks clear. Low pH (highly acidic water) can cause damage to your pool equipment including: pumps, filters, solar covers, liners and heaters. Adjust your alkalinity levels to ensure your pH is always balanced.

Filtering

  • Don’t forget to run your filter. Be sure your pool filter is running for at LEAST 12 hours each day. The more you run your pool filter, the cleaner your pool water, plain and simple. Make sure that all of your pool water runs through the filter at least once each day.
  • Don’t over backwash your filter system. The larger debris in your filter actually help to trap the smaller debris. The guideline is to backwash when the system is running 5-10 psi above the starting filter pressure (pressure with a clean filter).

Testing

  • Don’t skip your water testing. If you can’t do a full, comprehensive water test each week, be sure to at least test your free chlorine and pH levels. Bring a sample of your pool water into our Retail Store for a free, detailed analysis. We recommend a computer generated water test at least once a month.

Avoid these common pool care blunders and you will be well on your way to a safe and clean swimming pool.

  1. I wasn’t completely aware that we’re not supposed to shock our pool while there is sunlight until you said it. We’ve been doing it for as long as I can remember and I’m worried that we might not be taking care of our pool properly. Maybe it would be better to hire professionals who can do pool maintenance better.

    1. Zoe, we are so happy you found our blog helpful! Sometimes it makes sense to do your own pool maintenance and sometimes it makes the most sense to leave it to the professionals. There are many things to factor in when making this decision including your time, budget and experience caring for a pool or spa.

  2. That’s why our Dolphin robotic cleaner was not able to remove all the algae. We’ll be buying a different type of pool cleaner then.
