Does shocking a pool affect pH?Will shocking pool lower pH? Adding shock can actually raise your pH levels. If you use a calcium hypochlorite (cal-hypo) shock, this can raise your pH levels temporarily. So test your chemical levels regularly, especially after shocking.
Should you raise alkalinity or shock first?We always recommend adjusting alkalinity first as it's so important to the pH. Alkalinity is, after all, a measure of how much acid the water can neutralize. Properly balanced alkalinity leads to a properly balanced pool.
Does chlorine raise pH and alkalinity?Most people know that chlorine is an important chemical in keeping pool water safe for swimming. But adding too much chlorine can lower your pool's pH as well as its total alkalinity. When alkalinity falls, it is more difficult to maintain a stable pH.
What is the best way to raise pH and alkalinity in pool?If total alkalinity (TA) levels inside pool water are low, but pH levels are above 6.8, an alkalinity increaser (sodium bicarbonate: baking powder/soda) is added. When both the pH and TA need raising, a pH increaser (sodium carbonate: soda ash) is used.

What happens if pH is too low in pool?When your pool pH level is too low (below 7.2) you can experience: Irritated eyes and mucous membranes of swimmers. Damage or dimpling of your pool's plaster finish. Corroded metal parts such as ladders or diving board bases.
What is the fastest way to raise the pH in a pool?Baking soda and soda ash are two solutions you can add to water to raise a pool's pH. You can add either one directly to the pool. For the best results, walk around the edge while you dump the chemicals to distribute them evenly. Add 1.5 pounds of baking soda per 10,000 gallons of water.
Does too much chlorine raise pH?When chlorine levels are too high, the water's pH will start to decrease, which can eventually lead to corrosion. However, liquid chlorine has a pH of 13 and can cause the water's pH to increase.
Does chlorine shock raise pH?It will slightly raise your pH, so make sure you adjust pH while using it. As the name implies, it will also raise your calcium hardness levels in your pool slightly. It is sold in granular or in pucks/tablets. A close relative of calcium hypochlorite is sodium hypochlorite, commonly known as bleach.
What does shock do to a pool?What is a Pool Shock? So, what is pool shock, exactly? "Shocking” refers to the process of adding chlorine or non-chlorine pool chemicals to the water in order to raise the "free chlorine” level. The goal is to raise this level to a point where contaminants such as algae, chloramines and bacteria are destroyed.
Can I add shock and alkalinity at same time?Never add chemicals at the same time. Whether you're balancing your pool's water, shocking it, or adding specialty chemicals, you should let the pump run for a set period of time before adding another chemical or retesting the water.
Will shock work if pH is too high?Remember that a low pH level is crucial to successfully shocking a pool. At a pH level of 8.0, over half of your shock is ineffective and wasted. At a pH level of 7.2, however, over 90% of your shock will become active algae and bacteria killers.
How long after shock can I add alkalinity?A good rule of thumb is to never mix pool chemicals with each other. After adding Calcium Hypochlorite a user should always wait 24 hours before adding chemicals that would alter their pH. Adjusting pH or Total Alkalinty after adding Calcium Hypochlorite can cause the calcium to temporarily cloud the water.
What is the ideal pH for pool shock?The most optimal and effective pH level to shock a pool is anywhere between 7.2 and 7.4. If the pool water is anywhere outside of this range, the water will not be suitable for the shock, making the treatment significantly less effective. Once you have tested the water, you can adjust the pH level accordingly.
What to do after shocking pool?As we mentioned above, it's important to leave the filter to do its job after shocking a pool, and in general, you should allow the pump to run for at least eight hours a day during the swimming season. Water circulation and filtration problems can, though, be why the pool isn't clear.
How often should you shock your pool?HOW OFTEN SHOULD I SHOCK MY POOL? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
Can you over shock a pool?The simple answer is yes, you can over shock a pool. This is when the chlorine level in the water becomes too high and can be harmful to swimmers. When you shock your pool, you are raising the chlorine level to 10 times its normal level. This is done to kill off any bacteria or algae that may be present in your pool.
Why is my pool pH always high?Here are common causes of an alkaline pool: Algae can raise the pH. Adding strong liquid chlorine, calcium or lithium hypochlorite chlorine may raise it. Suddenly heating the water, whether from a pool heater or a string of sunny days, could up the pH.
How long to wait after shocking pool?The general rule for pool shock is to wait at least 24 hours. That's how long it takes for chlorine to work its magic and dissipate in your pool.
