Doheny's Closing Master Kit Instructions

First things first! Do not winterize pool until water is properly balanced and is clear of all algae growth, dirt and leaves.

Make sure you have Doheny's Water Test Strips to ensure pH and alkalinity levels are in balance.

You will need a pool vacuum or auto cleaner to remove dirt and debris from the floor of your pool.

Remove floating leaves and debris from the surface of your pool with a Doheny's Leaf Skimmer.

  • Step 1: Stop chlorination 24 hours prior to winterization.
  • Step 2: Pour entire bottle of Natural Chemistry METALfree into pool, making sure product is evenly distributed around entire pool
  • Step 3: Pour entire bottle of Natural Chemistry Pool Magic + PHOSfree into pool, also making sure product is evenly distributed.
  • Step 4: Wait 15 minutes and then slowly broadcast all packages of Doheny’s Chlorine Free Oxidizing Shock around the perimeter of the pool.
  • Step 5: If possible, allow pump to circulate for at least one hour to ensure that all chemicals disperse evenly.
  • Step 6: Lower water level and drain lines, pump, filter, and heater of all water according to manufacturer’s instructions. If you use pool anti-freeze, add it to your plumbing at this time.
  • Step 7: Punch holes in ALL dimples located on both sides of the floating dispenser. Slide foam collar onto dispenser as shown. Place floating dispenser in pool, smallest diameter down, which allows water to flow through perforated dimples. Do not throw in pool.
  • Step 8: Cover pool with a Winter Cover. Doheny’s offers top-quality Solid and Mesh type covers. Note: If Spring is unusually warm, lift up one end of the cover and look for signs of algae growth. If detected, an additional dose of Doheny’s Algaecide should be added.
  • Step 9: In Spring, remove water and debris from cover using a siphon or submersible pump available from Doheny’s. Then remove the cover, reconnect all plumbing, raise water, and discard winterizing floating dispenser.
  • Step 10: Add Doheny’s Pool Master Start-Up Kit, following directions, to your pool. Start your swimming season with sparkling, clean water.
