Clean and clear water is achieved through a program of regular pool maintenance, an effective pool filtration system, routine chemical maintenance including preventive measures and keeping the pool free of debris.

Pool Opening:


    Day 1

  1. Do not add pool chemicals if they cannot be properly circulated. Make sure the pool circulation system is running properly.
  2. Verify the skimmer baskets and pump strainer pot are clean and that the filter pressure is normal.
  3. With the pump running, verify the strainer pot is full of water and has no air in the pot and no leaks in the plumbing lines.
  4. If Algae is present, use SeaKlear® Yellow Klear along with SeaKlear Chlorine-Free Shock Oxidizer to kill the algae.
  5. Add SeaKear Natural Clarifier 4-8 ounces per 10,000 gallons or SeaKlear PRS® Stage 1 and SeaKlear PRS Stage 2 for severe cases.


    Day 2

  6. The filter should run for 24 hours during cleanup. Backwash or clean the filter as needed and empty skimming baskets and the strainer pot as needed.
  7. If the filter pressure does not decrease with normal cleaning procedures use of a filter cleaner may be required.
  8. Once the water is clear, set the filter to run six to eight hours a day. Filter cycles may vary.
  9. Brush the pool (brushing aids the clarifying process) and add 2 ounces of SeaKlear Natural Clarifier per 12,000 gallons to help clear the water.
  10. Use SeaKlear Algae Prevention & Remover according to directions to prevent the recurrence of algae blooms.


    Day 3

  11. Test the water for phosphates using an approved kit that tests for free orthophosphates. Treat with SeaKlear Phosphate Remover, according to label instructions. Backwash or clean the filter after 24 hours. Reset the filter cycle to six to eight hours a day.

Pool Closing:

  1. Vacuum and clean the pool thoroughly. Clean all debris from the skimmer and pump baskets.
  2. Shock the pool with SeaKlear Chlorine-Free Shock Oxidizer to break down organic waste in the water. Use 1 lb per 10,000 gallons. Make sure the filter is running.
  3. Balance the water: pH should be 7.2-7.8; Total Alkalinity should be 80-120 ppm.
  4. Add 16 ounces of SeaKlear Algae Prevention & Remover per 10,000 gallons of pool water. For concrete pools with salt systems use SeaKlear Problem Klear at a rate of 13 ounces per 10,000 gallons.
  5. Follow with 4 ounces of SeaKlear Natural Clarifier per 10,000 gallons. Run the filter for at least 8 hours.
  6. After 24 hours, add SeaKlear Phosphate Remover at a rate of 16 ounces per 10,000 gallons and let the filter run for another 24 hours.
  7. Clean or backwash the filter according to the manufacturer’s instructions.
  8. Raise the chlorine level to 6-8 ppm. For alternative chlorine systems, make sure there is a good residual of sanitizer in the water.
  9. Use SeaKlear Stain Prevention & Remover–Professional Strength to control metals throughout the winter. For pools with salt systems use SeaKlear Metal Klear.
  10. Thoroughly clean and inspect your winter cover for debris and holes. For extremely cold areas, turn off all equipment and make sure all timers and lights are shut down.
  11. Consult your professional dealer for more information on draining and preparing the system for freeze prevention.
