Here’s how to clean your pool’s filters:

Sand filter

Pool sand filters should be backwashed about once a week. Wondering how to clean a sand filter? Sand filters are easy to backwash, which means running the filter in reverse. Here are a few tips for how to backwash your pool’s sand filter:

  1. Stop your pool pump.
  2. Close all valves on the suction and return lines.
  3. Open pump cover and empty the filter basket.
  4. Return the pump cover.
  5. Open the drain outlet valve.
  6. Turn lever to backwash.
  7. Open valves on the suction and return lines.
  8. Restart your pool pump. Allow the filter to rinse for 1-2 minutes or until the sight glass is clear. *Don’t forget- if you have an electric heater, make sure it is OFF.
  9. Stop your pool pump.
  10. Turn lever to rinse, restart the pump and rinse for about 30 seconds.

Sand filters should be replaced every 3-6 years.

Diatomaceous Earth (DE) Filter

DE filters should be cleaned every 4-8 weeks. Cleaning a DE filter involves 3 basic steps:

  1. Backwash.
  2. Clean the manifolds and grids.
  3. Add new DE.

To backwash your DE filter, make sure the pool filter valve is in the backwash position and start the pool pump. When the water coming out of the discharge hose is clear, turn off the pump and return the valve to the normal position.

Once you’ve backwashed your DE filter, make sure your pool pump is turned off and open the air relief valve, remove the drain plug and drain the filter tank. Then open the DE filter. Depending on the type of DE filter you have, remove the manifold and take out the grids. Using a hose, flush the DE out of the filter grids and rinse out the tank.
After you clean the grids, place them back in the manifold inside the filter. Remove the strainer basket lid and fill the basket with water allowing water to run through the incoming line. Then lubricate the ring inside the tank. Replace the lid and tighten any clamps or bold on the pump.

Make sure to release the air in the tank by turning the air relief valve. Once that is complete it’s time to turn on the pool pump. When the water starts coming out, make sure to close the air relief valve.

Make sure your pump is running before you start adding DE into the filter. Don’t forget to calculate how much DE needs to go into the filter. Here’s how to calculate it:

  1. Look for how many square feet your DE filter is by looking on the filter or at the filter’s instruction manual.
  2. Take the square footage and divide by 5.
  3. The number you get is how many DE scoops you’ll need.

Mix the DE with water to create a creamy mixture. While your pump is running, pour the DE solution into the pool skimmer and the DE will be drawn to the filter and evenly distributed.

Allow the pump to run for 30 minutes before turning it off.

When cleaning your DE filter make sure to inspect it for any tears and replace it when needed.

13. Check your system pressure to make sure it’s within a normal range.

Shocking your pool

One of the easiest and most effective ways of keeping your pool clean is shocking your pool. To shock your pool means to add chlorine or non-chlorine pool chemicals to the water to raise the free chlorine (the desirable amount of chlorine available to sanitize water) level. Chlorine in your pool helps destroy algae, chloramines, and bacteria in your pool.

How often to shock pool

How often you shock your pool is ultimately up to you, but we recommend shocking it regularly every week or so to prevent bad smells and eye irritation from occurring.

Here also a few times you’ll want to shock your pool:

  • After a rainstorm
  • After heavy pool use
  • After a change in water level
  • After there has been poop in the pool

How to shock your pool

After you have skimmed your pool, vacuumed for sediment, brushed the walls, floors, and coves it’s time to shock your pool.

Here’s how to shock your pool:

  1. Check pH levels and make sure your pool is balanced.
  2. Prepare shock in a bucket.
  3. Make sure your pool pump is running.
  4. Pour shock mixture from the buck around the edges of the pool.
  5. Let the pump run for about 6 hours before testing the water.
  6. Wait for the free chlorine levels to drop between 1 and 3ppm before resuming use of the pool.
