The wait time between adding chemicals needs to be at least 10 minutes, as mentioned above. Under normal conditions, you will also be able to swim in the water roughly 10 minutes after all chemicals have been applied.
When adding pool chemicals, waiting around 10 to 20 minutes between additions is recommended. It's important to understand that pool chemicals are made of strong gasses and concentrated materials. Mixing these or adding them too quickly back-to-back could potentially cause unintended consequences, including explosions.
NEVER mix any chemicals together before adding to the pool. Generally speaking, almost all pool chemicals are incompatible in some way. Safe handling and application are key!
Since your chlorine levels will not return to normal right after you shock your pool, we recommend waiting at least 24 hours to add algaecide.
Liquid chlorine cannot be added with another chemical either (except stabiliser). Liquid chlorine for at least 8 hours before adding another chemical. Again, it is best practice to test first. Mixing acid and chlorine is very dangerous, it can combust and will cause very dangerous chlorine gas.
The simplest strategy is to follow them, remembering the two golden rules of adding chemicals: only add chemicals to a pool that is running, and only add chemicals to water, not water to chemicals.
Let the shock try to fight the algae first. Add algaecide about 24 hours after shock to finish the job and prevent future algae blooms.
Is it possible to shock your pool too much? Yes—excessive shocking of your pool will keep it at an elevated chlorine level. This will cause irritation of the skin and eyes as well as excessive wear and tear on your pool filter system, including excessive corrosion of all metal parts.
Low chlorine levels often cause green or hazy water, so if your water looks a little cloudy and you haven't shocked in a while, adding shock is the first step. It is always best to shock the pool in the evening, when the sun if off the water. If not, the sun will suck it out as fast as you add it.
Do-Not's. As for the 'do-not's,' you should never add water to chemicals, instead chemicals should be added to water. In the industry, people use the acronym AAA (always add acid) to remember this rule. Never pour chemicals too quickly or mix them together.
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.
Even when you add routine chemicals to your pool, it's smart to run the pump immediately afterward to properly disperse them.
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2–4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
Because pH and alkalinity adjustments affect one another, you should always correct the total alkalinity before pH. This is because proper total alkalinity will act as a buffer for pH, helping to prevent fluctuations in pH levels.
Test again, and when water balance levels are good, add your Stain Away, a stain, rust and scale preventer, followed by a dose of pool Clarifier. Allow these chemicals 8-12 hours to work before shocking the pool.
The acceptable range for pool water pH is 7.2-7.8, and the ideal pool pH is between 7.4 and 7.6. Water below a pH of 7.2 is too acidic, stinging your eyes, damaging pool liners and corroding equipment. Water above 7.8 is too alkaline and can cause skin irritation, cloudy water, and scale buildup.
While pool shock also works to sanitise your water, it is slightly different from using chlorine as part of a regular maintenance schedule. Shock dosing refers to adding a high concentration of chemical sanitiser in one dose to immediately increase the level of your sanitising chemicals and get your pool clean.
If you're dealing with an algae infestation, brush the pool after shocking to remove lingering debris and run the filter. Rinse or backwash your filter to avoid recontamination. If you've still got traces of algae, shock your pool again.
If you start in the evening, add a chlorine shock treatment that evening, and let the filter circulate overnight, and follow with the appropriate algaecide for your algae type the following day.
Most common swimming pool chemicals are incompatible with each other and should never be mixed. Mixing of organic chlorinating agents (such as trichloroisocyanuric acid) and inorganic chlorinating agents (such as sodium hypochlorite) can lead to fires, explosions and chlorine gas release.
Putting them in the same feeder can cause an explosion. After you add Calcium Hypochlorite, you will need to wait at least 24 hours before adding chemicals. This could alter their pH. Adjusting pH or Total Alkalinity after the addition of Calcium Hypochlorite will cause the calcium to cloud the water temporarily.
CHLORINE: Probably the best-known pool chemical, chlorine is a sanitiser that keeps algae and bacteria at bay. It comes in liquid, powder, and tablet forms. When water reacts with chlorine, it forms hypochlorous acid, which is the compound that fights bacteria.
