Get Rid Of Red Algae

If you have red algae, you can't play nice with it.  At the first sign, you must take the appropriate steps to getting rid of it.  First you should:

  • Remove everything you can from the pool including pool toys, floats, ladders and steps.  Give all of them a good cleaning with a 50/50 solution of bleach and water.
  • Bring the pool pH, pool alkalinity (TA), and water hardness into line. Never add chlorine without first adjusting these three.
  • Increase and maintain your chlorine level to 15 - 20 ppm using liquid chlorine or bleach.  Add chlorine morning and night.
  • Continuously run your filter and be sure to backwash 2 times per day until the water is clear once again
  • If you have a DE filter be sure to re-coat the grids with each backwash
  • Watch that the pool’s water level does not get below a minimum of 2” from the bottom of the skimmer
  • Use a good PolyQuat 60 algaecide specifically designed to lessen the chances of another algae bloom
  • There will be dead swimming pool algae on the bottom of the pool.  This can be filtered out through vacuuming the bottom of the pool once the water clears.
  • Keep brushing and vacuuming to rid the pool and any residual red algae and remember to keep filtering and backwashing to remove the swimming pool algae.  If you have a DE pool filter, you'll need to re-coat or recharge the grids with each backwash.  Spray out your cartridge filter.
  • Remember when you have an algae problem there is no quick fix.  It will take time, effort, and patience to clear up your pool.
  • When your swimming pool chlorine is down to  2 - 4 ppm the pool will be safe to swim in once again.
  • NEVER allow anyone to swim in the pool until the swimming pool algae is gone and the water has cleared up

How To Prevent Red Algae Returning

Maintaining Your Pool Goes A Long Way Toward Preventing Red Algae

  • Maintain your pool chemistry
  • Run your pump 8 to 12 hours per day during the Summer and 4 - 6 hours in the Winter or off-season if you keep your pool open all year
  • Brush your pool at least 2 x per week and vacuum when needed.  For plaster pools, a good wire brush can do wonders.  Never use a wire brush on a vinyl or fiberglass pool.
  • Clean your pool equipment, floats, and toys before putting them back in the pool.  Cut bleach in half with water and clean everything.
  • Also clean your swimsuits.  Make sure to wash them, not simply rinse them out.
