Want to know what products to use for certain pool problems? Here are a few suggestions!

High Metal Concentration
A high concentration of metals can discolor water and lead to staining and other problems. To remove existing stains, use Swim Things's All Surface Cleaner and brush stained area regularly to remove stains. To prevent metal stains in the future, include a dose of Stain Remover with your weekly maintenance routine.

Black Algae
Black Algae can be eliminated by using Swim Things's Total Pool Algaecide in conjunction with Swim Things's 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 using one of our Super Deluxe Brushes 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 Swim Things's 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 Swim Things's 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 7.2 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 Swim Things's Alkalinity 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 Swim Things's pH Plus or Swim Things's pH Minus until the pH level is between 7.2 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 Swim Things's Calcium Plus according to package instructions. Re-circulate the water for two to three hours and then 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.

IMPORTANT Please be advised that there is a difference between Free Chlorine or Bromine and Total Chlorine or Bromine. The Free Chlorine or Bromine readings are the only true level of available sanitizers in your pool's water. Total Chlorine or Bromine readings tend to give you a false reading based on how often you shock or oxidize your pool water.

Check the test kit you are using to make sure you are getting the correct readings necessary for this application. If you are using the Pool Test Strips, you are fine and are using the correct reading. If you are using the Comprehensive Pool Test Kit, double check to make sure you have the reading for Free Chlorine or Bromine.
