Spring Opening: How to Treat and Prevent Algae

Green pools are often caused by algae growth in the water. This could take on the form of patches of green, yellow or black substances that fluffs into the water when touched or stirred. The water may have discoloration, usually green.


use your automatic vacuum, as there is no option of vacuuming on waste/drain.

  • 1.

    Bring a pool water sample into Buds for water balance assistance.

  • 2.

    Remove large organic debris from the bottom of the pool with deep leaf net.

  • 3.

    Add DEGREASER generously throughout the pool and let circulate for 24hrs

  • 4.

    Turn dial on filter to waste/drain and then using a manual vacuum only, remove debris from the bottom and sides of the pool. If cartridge filter doesn’t have a bypass, cartridges will need to be rinsed every 3-5 minutes while vacuuming.

  • 5.

    Top up pool with fresh water.

  • 6.

    Adjust pH to 7.2 as per kit instructions.

  • 7.

    Add a Solution 48 KIT to the pool, following the directions enclosed and two kits will be needed if pool volume exceeds 90 000L.

  • 8.

    Brush down the walls and the floor of the pool. Be sure to brush areas on and around steps, ladders and corners very well

  • 9.

    Use KLEAR SOK in skimmer basket only with sand filters.

  • 10.

    24 hours after kit add Algi Pro 40.

  • 11.

    After 48 hours, backwash the sand filter for approximately 3-5 minutes or rinse cartridges.


All dead organic matter may need to be manually vacuumed on waste/drain after treatment in order to by-pass the filter or cartridges rinsed every 3-5 minutes while vacuuming.

  • As soon as the pool clears, be sure to chemically clean your filter using filter cleaner. This will remove any remaining algae spores that backwashing/rinsing will not get rid of.
  • If pool does not clear bring back a water sample. If the water is clear, balance accordingly. If you have a sand filter that has never been chemically cleaned and the sand is 3-5 years old, we highly recommend that you change the sand before treating for algae.

Always ensure pump and filter systems run continuously until pool is cleared.
