| High Metal Concentration
A high concentration of metals can discolor water and lead to staining and other problems. To remove existing stains, use Doheny's Water Warehouse All Surface Cleaner and brush stained area regularly to remove stains. To prevent metal stains in the future, include a dose of Water Warehouse Stain Remover with your weekly maintenance routine. Black Algae Black Algae can be eliminated by using Doheny's Water Warehouse Total Pool Algaecide in conjunction with Doheny's Water Warehouse Shock specific to your pool following the recommended dosage on the package. Run your swimming pool filter overnight to circulate the shock throughout the pool's water paying special attention to areas with existing algae blooms. You may need to backwash your filter during and after this process to prevent high pressure readings. You will also need to brush the existing algae spots daily to loosen and remove any algae debris until algae spots disappear. To prevent future algae blooms, shock your pool regularly and add a weekly maintenance dosage of the Doheny's Water Warehouse Pool Algaecide that is right for your pool. Low pH If the pH in your water is low it can lead to corrosion, rapid decrease in chlorine/bromine residual, and also lead to irritation of the eyes and skin of swimmers.This can be resolved by adding Doheny's Water Warehouse pH Plus according to package instructions. Run your swimming pool filter for two to three hours to circulate and then re-test your water. Repeat as necessary until pH levels are between 7.4 and 7.6 ppm. Low pH and Alkalinity In order to bring your pool water back into balance, we suggest the following: First you must correct the alkalinity level by adding Doheny's Water Warehouse Alkalinity Up according to package instructions. Re-circulate for two to three hours and then re-test the water. Repeat as necessary until the alkalinity level is between 80 and 120 ppm. Because pH and alkalinity levels are so closely related and directly affect each other, it is recommended that you check your pH level the following day and adjust accordingly with either Doheny's Water Warehouse pH Plus or pH Minus until the pH level is between 7.4 and 7.6 ppm. Low Calcium Hardness If the calcium hardness level of your pool water is too low it can lead to corrosion on heating elements along with other pool surfaces. To increase the calcium hardness of your pool water, add Doheny's Water Warehouse Calcium Plus according to package instructions. Re- test the water the following day. Repeat as needed until the calcium hardness level of your pool is between the recommended range of 200 to 400 ppm. NOTE: There is a difference between FREE AVAILABLE CHLORINE or BROMINE and Total Chlorine or Bromine. Free Chlorine or Bromine readings are the level of available sanitizers in your pool's water. Total Chlorine or Bromine readings that are above your FREE AVAILABLE level indicate that your pool needs to be shocked. In order to maintain Properly Balanced & Clear Pool Water, it is recomended that your filter system run continuously 24/7. SOLVING POOL WATER PROBLEMS |
