"There aren't a lot of pool companies who will replace an above ground liner. I didn't think the customer service was great and it seems overpriced, but there aren't a lot of options so I appreciate they came to do this work."

Pool and Spa Servicing FAQs, answered by experts

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.

Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.

A hot tub cover's lifespan is typically between three and seven years, with an average of five to seven years for a well-maintained one. The quality of the cover is a major factor; lower-quality polyester or vinyl soft covers can tear easily with regular use.

To extend the life of your cover, proper maintenance is key. This includes:

  • Keeping the cover clean, dry, and out of the sun. Use a soft cloth and mild dish soap for cleaning.

  • Applying a vinyl protectant spray.

  • Cleaning the underside with a chlorine spray.

  • Using a cover lift to prevent damage from rough handling.

  • Protecting it from harsh weather.

  • Keeping children and pets off the cover.

Investing in a high-quality cover and checking for a warranty at the time of purchase can also contribute to its longevity.
