Maintenance

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.

Balanced Water

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.

PARAMETER WHAT IS IT? WHEN TO TEST IDEAL RANGE PRODUCT USED TO
ADJUST LEVELS
pH A measure of the water's acidity Every day 7.2-7.8* hth® pH increaser or hth® pH decreaser
Free Available Chlorine (FAC) The amount of active chlorine in the water Every day 1-4 ppm when using chlorine as the sanitizer Any hth® granular or tablet chlorine sanitizer according to label directions
Total Alkalinity (TA) The water's ability to keep pH at a proper level Once a week 60-120 ppm hth® alkalinity increaser
Calcium Hardness (CH) The amount of dissolved calcium in the water Monthly Acceptable: 200-1000 ppm, Ideal: 200-500 ppm hth® calcium increaser
Cyanuric Acid / Stabilizer (CYA)** The amount of stabilizer available to prevent the degradation of FAC caused by the sun's UV rays Twice a season Ideal: 20-50 ppm, DO NOT EXCEED 100 ppm hth® stabilizer

Opening Your Pool

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 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 the hth® Leaf Skimmer to scoop up all surface and submerged debris.
  • Clean the pool floor and walls with the hth® 18" 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.
  • Turn on filter pump and check the circulation system for leaks.
  • Check the skimmer, drain and filter to make sure they are functioning properly.
  • Use the hth® Multi-surface Vacuum Head along with the hth® 35' Universal Swimming Pool Vacuum Hose to remove any remaining debris.
  • Run the filter for 12 hours.


Preparing the Pool Water

  • Test the water using the hth® 6-wat 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.

CAUTION

Please read the following important reminders before adding pool chemicals to water:

  • NEVER mix products with other products or dissolve before use.
  • NEVER enter into any pool with FAC levels above 4 ppm due to risk of bodily harm.
Closing Your Pool

Cold Climate

  • Test and adjust water balance using hth® 6-way multi-purpose test strips or other hth® test kits or strips.
  • Use the hth® pool care kit for opening and closing your pool. Carefully follow label directions for order of addition and proper dosage for each product.
  • Clean pool by thoroughly vacuuming and removing any floating debris.
  • Follow equipment manufacturer's directions to winterize the pump, filter and other pool equipment.


Warm Climate

  • Decrease pump/filter cycle to half of its swimming season setting, but not less than 4 hours / day.
  • Test the water balance weekly using the hth® 6-way multi-purpose test strips or other hth® test kits or strips. Adjust as needed.
  • Adjust free available chlorine (FAC) to 1-4 ppm.
  • Maintain pool equipment following manufacturers' instructions for care of equipment with the pool is closed.
  • Clean the skimmer baskets and pump hair and lint strainer weekly or as needed.
  • Vacuum the pool as needed.
  • If the pool will be covered shock treat the water a few hours before applying the cover. Follow directions on the hth® shock product label.
