1. What is your pH reading?

pH is high – ( over 7.6)

  • If your pH is high, you should add pHix it down. It is also called Sodium Bisulphate or acid
  • Add pHix it down as per the chart on the container.
  • Simply broadcast it across the pool, run the filter for four (4) hours and re-test the pH.
  • KEEPING THE pH OF YOUR POOL WITHIN RANGE WILL KEEP OTHER CHEMICALS WORKING PROPERLY.
  •  THE pH LEVEL OF YOUR POOL SHOULD BE BETWEEN 7.2 - 7.6.

pH is low – ( under 7.2)

  • If your pH is low, you should add pHix it up
  • It is also called Soda Ash or Sodium Carbonate
  • Add pHix it up as per the chart on the container.
  • Simply broadcast it across the pool, run the filter for four (4) hours and re-test the pH.
  • KEEPING THE pH LEVEL OF YOUR POOL WITHIN RANGE HELPS OTHER CHEMICALS WORK MORE EFFECTIVLY.
  • THE pH LEVEL OF YOUR POOL SHOULD BE BETWEEN 7.2 - 7.6.

2. What is the difference between pH and Alkalinity?

  • pH is the scale which measures the balance between acids and alkalis (bases). Your chemicals work their best when the pH level is in the ideal range which is: 7.2 - 7.6
  • Alkalinity- Is a measure of just the alkalis. If this is not correct, it will affect your pH readings. Your alkalinity level should be between 80 ppms - 120 ppms. If your alkalinity level is low: broadcast Alka pHix across your pool. (amount needed varies, see bottle for amount needed)Run your filter for 4 hours and test your alkalinity again. Repeat until you your alkalinity level falls into the correct range. If your alkalinity level is high: broadcast pHix It Down to your pool water, run filter for 4 hrs and test alkalinity level of water again.(amount needed varies, see bottle for amount needed)

3. My chlorine level has not been checked or is not correct.

  • If you are having trouble with your chlorine level, you should check and adjust pH accordingly.
  • Then add Chlor Guard to the water to help extend the life of the chlorine.
  • Chlor Guard is a chemical which helps prolong the life of chlorine in the water even in direct sunlight.

Chlorine level is too high

  • If your chlorine level is too high, the best thing to do is to either discontinue adding chlorine to the pool until the level drops, or you can drain about 1 foot of water out of pool and replace with fresh water.
  • If your chlorine level is high due to Combined Chlorine, which is a weak, ineffective form of chlorine which is formed when chlorine oxidizes nitrogen compounds such as urine, perspiration, etc., simply add Fast Blast to the pool.
  • This will eliminate the Combined Chlorine and make the Free Chlorine in the pool more effective.
  • The most effective way to check for free chlorine is with The Easy Check Pro 5 in 1 Test Strips.

Chlorine level is too low

  • If your chlorine level is too low, The best thing to do is to check and adjust the pH accordingly and shock the pool using a CHLORINE BASED SHOCK TREATMENT { e.g, green out }.
  • Shocking is the burning out by oxidation through super-chlorination of contaminants which put a demand on your chlorine.
  • It is not recommended to use the following: Quick Tabs, Gold Dust, or Slow Tabs as a shock treatment.

4. I have not added a water clarifier.

  • Check and adjust pH accordingly.
  • Then you should add a clarifier.
  • This will bring the smaller particles together, then they will drop to the bottom of the pool where they can be vacuumed out.
  • You should use Krystal Klear which is a concentrated clarifying agent.
  • Pour it into the pool by the return.
  • Then, run the filter for 4-6 hours, turn off the filter for 12 hours and then vacuum the bottom of the pool.

5. I used a water clarifier and the water is clearer.

  • If you have added water clarifier and the water is getting clearer, the best thing to do is to re-apply the clarifier.
  • The proper way to add a clarifier is to first check and adjust pH accordingly.
  • Then you should add the clarifier.
  • This will bring the smaller particles together, then they will drop to the bottom of the pool where they can be vacuumed out.
  • You should use Krystal Klear which is a concentrated clarifying agent. Pour it into the pool by the return.
  • Then, run the filter for 4-6 hours, turn off the filter for 12 hours and then vacuum the bottom of the pool.

6. I have done all the above and my water is still cloudy.

  • If you have confirmed that your water is properly balanced, your cloudy water may be caused by a malfunctioning filter. Here are some simple things to check: Are your hoses connected to the correct ports? Consult your filter owners manual for proper connections.
  • If you are using a sand filter, have you changed the sand this season?
  • If you are using a DE filter, do you see DE returning back into the pool? If so it's time to have your filter serviced.
  • If you are using a cartridge filter make sure that the cartridge is seated properly and not damaged in any way.
