Pool Maintenance - Great Lakes Ace Hardware Store Header

Before you begin your pool care program, you'll need to calculate your pool capacity. This will help determine the amount of chlorinator, sanitizer, shock treatment, and other chemicals your pool or spa needs.


To ensure your water is balanced we have created the following chart with ideal levels and the recommended HTH® pool care products necessary to adjust your levels.



When it's time to open your pool for the swimming season, choose HTH® pool care products to prepare your water. There are two essential elements to ready your pool for the season: ensuring the equipment is in proper working order and balancing the water. Use the HTH® pool care kit for opening and closing in addition to the steps below.

Preparing the Pool Water
  • Test the water using the HTH® 6-way multi purpose strips, or other HTH® test kits or strips.
  • Adjust the TA, pH, FAC, and CH to the ideal levels recommended in the Balanced Pool Care Chart.
  • If needed, stabilize the water using HTH® stabilizer.
  • Shock treat pool water with an HTH® shock product.
  • Continue routine maintenance following the 4-Step Program for the entire season.

Preparing the Equipment
  • Remove any water and debris that have accumulated on your pool cover during the winter.
  • Take off the pool cover. Clean the cover to prevent mildew and premature deterioration.
  • Reconnect all plumbing and electrical connections for the pump, filter, and circulation system.
  • Make sure the skimmer(s), filter(s), pump(s), drain(s) and other equipment are clean and free of winter debris.
  • Use a leaf skimmer to scoop up all surface and submerged debris.
  • Clean the pool floor and walls with a curved wall brush.
  • Add water to the pool to bring it up to the proper level.
  • Make sure all hoses and electrical hookups are in working order.

  • Drain pump, filter, heater and all other equipment according to manufacturer’s directions. Properly store all equipment indoors to prevent damage from freezing temperatures. Follow manufacturer’s directions for lubrication and proper storage.
