When you shock a pool,
you test and adjust the pH level for
a reason. With that said, if you shock a pool outside of the 7.2 to 7.4 pH range, not only will you waste a significant amount of the chlorine used, you will also end up with cloudy water.
Does chlorine free shock raise pH?
Because chlorine-
free shocks have a lower pH than their chlorinated counterparts
, swimming can resume just 15 minutes after the shock it added. … For this reason, it is best used when the water is murky or the combined chlorine is too high.
What pool shock does not raise pH?
Dichlor Shock
Features
Stabilized so it lasts longer than non-stabilized shock. Does not raise the pH level (6.0 – 7.0). Perfect for all types of pools.
Does chlorine cause pH to go up or down?
Pool Chemicals
Granulated or liquid chlorine is alkaline and, therefore,
tends to raise the pH level
. Bromine is more neutral and has a minimal effect on pH, while chlorine gas is acidic and lowers pH.
Does liquid shock affect pH?
Using Liquid shock or liquid bleach regularly will increase your pH so make sure you keep an eye on your pH and alkalinity levels. … This also
does not affect your pH
so there is no change in your water chemistry and keeps the water balanced. The Granular Dichlor has 56% of available chlorine.
Can I use shock instead of chlorine?
SKIMMER NOTES: No. Chlorine and shock are not the same thing.
Shock has a more intense chemical strength than the traditional chlorine sanitizers, and it also differs in how you should apply it to your swimming pool. Short answer: No. Chlorine sanitizers and shock are similar but different
in strength
.
Can I use pool shock instead of chlorine?
1) What is the difference between chlorine and shock? … Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and
shock
.
How long after adding pH up can you add shock?
Most balancing chemicals, such as pH, alkalinity, and calcium hardness, will become incorporated into the water within an hour of adding them, at which time swimming is safe. Shock takes longer to adjust with the pool water, so waiting
overnight after
shocking before you swim is recommended.
What can I use instead of shock for pool?
Baking soda
— Baking soda will raise both the H and the alkalinity of a pool, improving stability and clarity. Many commercial products contain baking soda. Obviously, you will have to buy it in bulk.
How long after shock can I add chlorine?
You should
wait one hour per pound of shock product added
, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool. As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.
Will Shocking pool lower pH?
When you shock a pool,
you test and adjust the pH level
for a reason. With that said, if you shock a pool outside of the 7.2 to 7.4 pH range, not only will you waste a significant amount of the chlorine used, you will also end up with cloudy water.
Does Rain lower pH in pool?
Effect on Pool Water pH
Since rain is diluting your pool, you may expect that it will reduce the acidity of your pool water. However, all rain in the US is acidic due to pollution, so
rain actually decreases your pool’s pH
– in other words, the pool water becomes more acidic.
How do you tell if there is too much chlorine in a pool?
If the chlorine smell is very strong, however, you may soon spot
“red-eyed” swimmers emerging from the pool
. That’s when the pool water is assumed to have “too much chlorine” in it. Ironically, a strong chemical smell around the pool and “swimmer red eye” may be signs that there is not enough chlorine in the water.
Is liquid chlorine and shock the same?
Liquid chlorine and
granular shock have the same active chemical that sanitizes your pool
, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
Is liquid chlorine better than granular?
Liquid chlorine may be a good choice if you have a large pool, but the costs associated with it, and the available chlorine per pound could mean that
chlorine granules are
the better option. In the end, both liquid chlorine and chlorine granules will do their job and keep your pool clean and clear.
Which is better liquid chlorine or powder?
Powdered chlorine
is the most typical form of chlorine used in a domestic pool environment. It is typically only slightly more expensive than liquid chlorine but it is much easier to use and has a lower pH, therefore has less impact on your pool’s balance when used.
