Frequently Asked Questions
Q.What should I do to get rid of the stains on the bottom and walls of my pool?
A.If the stains do not brush off, you have dissolved metals. When you add shock, metals can fall out of solution and attach to the pool surface. The stains can appear black, blue, or orange. Adjust the pH and total alkalinity to recommended levels. Wait until the chlorine level drops to 1 part per million (ppm), pre-dissolve “stain remover’ at the rate of 1 lb. per 5,000 gallons of pool water in a 4 gallon pail of water. Pour mixture into pool and allow it to circulate for 1 hour. Then add 1 quart of “pool magnet plus’ per 10,000 gallons of pool water. This treatment is specifically recommended for removal of stains caused by metals on pool surfaces including vinyl, fiberglass, plaster and tile. Be sure to test and adjust ph and total alkalinity (TA) after procedure is complete.
Q. Right before a pool party, we realized we had forgotten to shock our pool. Is there a quick way to shock the pool?
A. Yes! The next time you want to be able to swim in 15 minutes after shocking your pool, use BioGuard Smart Shock or Oxysheen. Both of these pool products restore the sparkle in your water, and remove non-filterable compounds. In addition to working fast, they are easy to use. Just add one bag of Oxysheen per 10,000 gallons or one pound of Smart Shocker for every 12,000 gallons, following label instructions. BioGuard Smart Shock is compatible with all pool surfaces and filter types, and can be used in pools using either chlorine or bromine.
Q. I don’t seem to be able to get a high enough chlorine reading, even after increasing my chlorine additions. What is my problem?
A. Your problem is known as a high chlorine demand, and means your pool water is unable to maintain an adequate chlorine level. This problem should be corrected as quickly as possible. First, check the filter to ensure proper operation. Make sure your filter has been backwashed and/or cleaned. Next check the pH level. If the reading is below 7.4, add the appropriate amount of BioGuard Balance Pak 200. Check the chlorine stabilizer (cyanuric acid) level. IF the level is below 40 ppm, add BioGuard Stabilizer 100 according to label instructions. Now, turn on the pump and add twice the normal application of BioGuard Burn Out Extreme or Burn Out 35. A normal application of Burn Out Extreme is 1 bag per 10,000 gallons of water, and a typical Burn Out 35 application is 1 bag per 6,000 gallons.
Q.I have insects above and below the surface of my pool water. What else can I do besides using a skimmer?
A. An application of BioGuard Back Up Algae Inhibitor will drown the remaining insects. Algaecide decreases water surface tension, reducing an insect’s ability to carry ‘breathing air’ below the water. A shock treatment will also kill insects or drive them away from the pool Vacuum dead insects from the bottom of your pool after shocking.
Q. After adding shock to my pool, when is it okay to swim?
A. The best time to add shock is in the evening. Before re-entering the pool, test your chlorine level. The pool is ready for swimming once the chlorine level is below 3.0ppm. Swimmers may re-enter the pool 15 minutes after it has been shocked if Smart Shock is used.
Q. My pool water turned green almost immediately after I shocked it. How do I clear up the water?
A. the discoloration is likely the result of metals in your pool water. When the shock was added, the metals came or fell out of solution, resulting in a brown, turquoise, purple, or green discoloration to the water. Discolorations can occur when untreated metals are present in your pool water from corroding equipment, source water, dirt, toys, or pennies. To clear up the water, add three quarts of BioGuard Pool Magnet Plus per 10,000 gallons of water. One hour after adding product check your pH and adjust as needed.
Q. Why does our pool water sometimes burn our eyes?
A. This can be caused by an improper pH. Test and adjust your pH to 7.4-7.6. Another culprit can be chloramines. Also known as combined chlorine, this problem results when the chlorine you are using attacks and combines with compounds in your pool (bacteria, sweat, suntan lotion) causing irritation to your eyes and a chlorine odor. To treat for combine chlorine, add 1 lb. of shock per 10,000 gallons of pool water. You should shock twice a month, after heavy pool use, and after rainstorms to prevent future problems. If you have a vinyl or colored plaster pool, use BioGuard Burn Out 35 to avoid bleaching surfaces.
Q. My pool water is cloudy. What’s wrong?
A. Nine times out of ten, cloudy water is the byproduct of too little chlorine in the pool. Make sure your chlorine level is at least 3 parts per million by using your test kit or test strips. To ensure clear water, check your filter operation and shock the pool with double your recommended dosage of Burn Out 35 or Burn Out Extreme. Remember to leave your cover off for at least 8 hours after shocking and be sure to test the water’s chlorine level before allowing swimmers to enter the pool.
