There could be a number of causes…

1. Dirty Filter

   Solution: Backwash filter or clean cartridge filters with filter cleaner. If problem persists a filter or sand change may be necessary. Please contact us for assistance.

2. PH Level Too High

   Solution: Test pH and total alkalinity. Add pH down as directed. Adjust as required. (pH down could be muriatic acid or dry acid) Please contact us for ordering information.

3. Free Chlorine Low

   Solution: Test for chlorine residual and adjust as needed. Pool may require a shock treatment, shock as directed by product labeling.

4. Backwashing Sand Filter Too Frequently

   Solution: Backwash less frequently, only as recommended by filter manufacturers directions. Only backwash based on PSI and not on a timed schedule.

5. Dissolved Metals In Water

   Solution: Use a metal out to control metals in water such as Metal Klear or Revive, prevent staining and scale formation.

Cause: Green Algae

Solution: Check chlorine level and raise level with shock if necessary, chlorine must be at 30ppm chlorine to effectively kill algae. Vacuum pool directly to waste. Use a clarifier once the water becomes milky color. Backwash daily until pool is clear. Use our request service page to have the necessary chemicals delivered right to your door!

Cause: Black Algae

Solution: Use a Black Algaecide as directed. Put chlorine directly on affected areas. Brush daily until gone. If Algae does not get better in 3 days, repeat treatment.

Cause: Mustard Algae

Use a filter cleanser to remove algae from your filter. Brush affected areas. Use an Algaecide specifically for Yellow Algae. Use a clarifier once the algae is dead to remove from water.

Cause: Iron Or Maganese Dissolved In Water

Solution: Use Revive to suspend and inactivate stain causing minerals.

Cause: Dissolved Copper From Fill Water Or Corrosion Of Copper Pipes Or Heater

Solution: Use Metal remover such as Revive or Metal Klear. Test and adjust pH and total alkalinity.

There could be a couple of causes…

1. Metals In Water

   Solution: Use stain remover to remove stains. Follow treatment with Metal Klear.

2. Unbalanced Water

   Solution: Make necessary pH and total alkalinity adjustments, low pH corrodes metal in pipes and equipment introducing metals to the water.

Cause: PH Or Total Alkalinity Too High Calcium Content Too High

Solution: Correct with pH Down as directed. Dilute pool water with water of lower hardness.

There could be a couple of causes…

1. Combined Chlorine Level Too High

   Solution: shock treat with Super Shock-It. Then test for free chlorine residual and adjust to maintain residual of 1-3ppm. To remove Combined Chlorine you must raise the total chlorine to 10 times the combined chlorine level.

2. PH Too Low Or Too High

   Solution: Test pH and correct with pH up or pH down.

Cause: Combined Chlorine Level Too High

Solution: shock treat with Super Shock-It. Then test for free chlorine residual and adjust to maintain residual of 1-3ppm. To remove Combined Chlorine you must raise the total chlorine to 10 times the combined chlorine level

Cause: Grease And Oil From Swimmers (High TDS)

Solution: use and enzyme action Natural Klear or Natural Chemistry’s Pool 1st Aid to remove oils and lotions. Diluting the pool water may be necessary. Use our request service page to have the necessary chemicals delivered right to your door!
