Sand Filter Vessel Wash and Cleaning (With Sand Or Glass Pack Media):

** Bleach Treat a Sand or Glass Pack Media Filter


  1. If you have sand or Glass Pack media in sand filter vessel from last year/season or have not bleach treated in the last year, complete a filter media bleach or acid treatment cycle in the spring upon pool start up.
  2. If you have sand media inside sand filter vessel, consider replacing it with Glass Pack media. 10X performance improvement filtration to 2-5 microns vs 50 microns with sand. 10 Year Life with GlassPack vs 1-3 years with sand. Backwash every 4-6 weeks with Glass Pack vs 1-2 weeks with sand. Save water, energy, money, hassle and get clearer water with Glass Pack media.
  3. Backwash Filter 2.5 minutes.
  4. Rinse Filter 30 seconds or until sight glass clear.
  5. Loosen filter diverter valve collar screw, remove it, open and inspect filter, Unscrew the drain plug.
  6. Drain the water until the media is visible. ( This may take a while.) Replace the drain plug.
  7. Remove any debris.
  8. Make sure media is within 10-12″ of the top. Add media as necessary.
  9. Pour 2 gallons bleach per 300LB of Glass Pack media in filter.  Pour 2 gallons bleach or liquid muriatic acid per 300LB of sand media in filter.
  10. Wait 8-12 hours with pump off. Then put filter valve back together.
  11. Backwash Filter 2.5 minutes.
  12. Rinse Filter 30 seconds or until sight glass clear.


DE Filter Wash and Cleaning

**DE Filter Wash and Cleaning. See video here:


  1. Have the DE filter broken down for cleaning and checked for broken grids.
  2. Remove the grids.
  3. Soak the grids in a 2 parts water to 1 part liquid muriatic acid solution for 12 hours. (Soaking grids is critical twice yearly.)
  4. Reassemble the grids.
  5. Add DE powder per instructions.


How and When to Clean the Electrodes

The electrodes in a pool system need to be cleaned 2 times per year. Also clean them if there is visible build-up on the electrodes. DO NOT TAKE THE ELECTRODES OUT OF THE CHAMBER TO CLEAN THEM. Remove the entire chamber and place it in an acid and water solution, 5 parts water and one part acid.


  1. Make sure the pump and filter are off and the valves are closed.
  2. Slip the wires off of the metal tabs on the outside of the chamber and unscrew the chamber from the return line. If the unions don’t loosen by hand, try a strap wrench. Be careful not to crack the chamber.
  3. In a 5 gallon bucket, mix a solution of 5 parts water to 1 part acid. Pour the water in first and then the acid.
  4. Place the entire electrode chamber in the solution for 10-15 minutes. Allow the solution to do the work.
  5. If the chamber isn’t clean after 10-15 minutes, let the chamber soak longer, but not longer than about 1 hour.
  6. Do not scrub or scrap the electrodes. Using tools to scrape the electrodes will damage them.
  7. Remove the chamber from the solution and rinse in fresh water.
  8. Replace the chamber inline and hand tighten the unions.
  9. Replace the wires on the chamber. Red and green wires go to the copper electrodes and the black and white wires go to the titanium electrodes.
