Not Brushing Your Pool
You already know how important it is to vacuum your pool regularly to keep scum and gunk from building up and ruining your swim.
But just like your teeth or a hutch of Angora rabbits, your pool needs a good brushing to look its best. Whether you vacuum your pool manually or automatically, follow up with a good brushing.
What Are The Different Types Of Pool Shock
With different pool shocks or shock products are available, how do you know which one is best for your pool?
Heres a breakdown of the top 3 pool shocks.
- Calcium Hypochlorite: Commonly referred to as cal-hypo, this shock is the most popular option, and contains 70% chlorine for killing algae and contaminants. Its unstabilized nature means the sun will burn it off and it wont increase cyanuric acid levels in your pool.
Cal-hypo has a high pH and will temporarily raise those levels, so its a good choice for pools that test at a normal or low pH level. Of note, your water may become temporarily cloudy, and cal-hypo may also increase your waters calcium hardness.
- Dichlor: Sodium dichlor is 55% chlorine and stabilized, which means it contains CYA. This makes it last longer in your pool water than cal-hypo, and the lower pH level and lack of calcium will keep the pool from getting cloudy.
However, because it contains CYA, CYA levels can increase. This has to be carefully monitored otherwise you may need to invest in a CYA reducer, or even drain/dilute your pool.
- Non-Chlorine Shock: Also known as Potassium Monopersulfate , this is a chlorine-free shock that oxidizes contaminants, but wont rid the pool of bacteria. Compared to chlorinated shock, you can use MPS shock at any time of day and be swimming in the pool 15 minutes later. Its pH neutral so your level wont fluctuate, and by focusing on oxidation, it frees up the pools chlorine to be more efficient at sanitizing.
Hth 67032 1qt Super Algae Guard Swimming Pool Algaecide Cleanser
If youre looking to know the best pool shock to use, you should give this HTH product a try. This algae guard prevents and kills yellow, black, and green algae. You need around four fluid ounces in every 10,000-gallon of water.

Why Do You Need To Use Pool Shock
A pool is an easy place for bacteria to grow and accumulate. While you may think grabbing the pool net and scooping up leaves and debris from your pool is enough to keep it sanitary, the truth is that is only part of the cleaning process. Bacteria that you cannot see can do more damage to your water and if left unchecked, can lead to algae growths that will make it impossible to enjoy your pool. Shocking your pool regularly is a lot easier than you may think and it is essential to keep your pool pristine.

The two main ingredients to know are calcium hypochlorite, found in In The Swim Chlorine Pool Shock, and sodium dichlor, found in Clorox Pool& Spa Shock XtraBlue. Calcium hypochlorite is affordable, quick, and very strong at cleaning up bacteria and raising the chlorine levels. Sodium-dichlor has the advantage of lasting longer, but usually has a slower application process.

Tips On Pool Shock To Use
The type of pool shock you use will depend on the water chemistry and why you need to shock your pool.
- For green water, use calcium hypochlorite shocks.
- For weekly maintenance, use calcium hypochlorite, sodium di-chlor, or potassium mono persulfate shock.
From there, know the type of pool before you add your pool shock.
Why Shock Your Pool

Make A Shocking Solution

Hth 42033 Super 3 Chlorinating Tablets

The product is compatible with salt-water and vinyl-liner pools. The manufacturer recommends that when you use the tablet, you run the swimming pool pump for a minimum of eight hours a day for proper sanitization.

Warning About Poop In The Pool Water
On any given day in your chlorinated pool, youre just one toddler diaper or animal poop away from dangerous recreational water illnesses.
These illnesses are caused by organisms such as Cryptosporidium, Giardia, and E. Coli, as well as symptoms such as severe diarrhea, which will all make you and anyone swimming in your contaminated pool water very sick.
Which Is The Best Pool Shock To Use
The type of shock that you use depends on the chemistry of the water and the reason for doing the shocking:
- If you have water that is green, you should use the Calcium Hypochlorite.
- If you are doing weekly maintenance and the water looks clean, any of the three types will work.
- You should use the non-chlorine shock every other week or before you have a lot of swimmers in the pool.
- The non-chlorine shock should also be used if bromine is the primary sanitizer of your pool.
1. For Vinyl Pools
Vinyl, or polyvinyl chloride , is made by joining chlorine and ethylene. It is then made into rolls of a thin, flexible material that is used to line both in-ground and above ground pools.
Even though vinyl is made from chlorine, having your water over-chlorinated for too long of a period will draw resins from the vinyl. This will cause it to lose its plasticity. Vinyl liners getting bleached is another problem caused when powdered chlorine shock is added to a pool and sinks to the bottom before it has a chance to dissolve.
2. For Fiberglass Pools
3. For Concrete Pools
How Often Should You Shock Your Pool
The frequency of pool shocking isnt set in stone, and it really only needs to be done when your water starts going haywire.
Some things youll be able to visually see , but most water pollutants will be invisible.
There are some pool owners who like to shock once a week to keep the water its cleanest, while others will do it on a 3-week or monthly cycle.
Shocking frequency also depends on how much use the pool is getting, and what kind of weather its being subjected to. Heavy rainfall and storms can disrupt the pool waters chemical makeup by introducing backyard debris and air pollutants like dust and pollen spores into the water.
Likewise, an increase in the number of people using the pool will bring in more organic bacteria, resulting in a chlorine level decrease. If you have a pool party, youll most likely have to shock the pool once its over.
Youll also want to apply shock treatment when opening the pool, and closing it down for the season.
On opening, after youve balanced its pH level, shocking will sanitize and oxidize the pool, restoring its clear water. On closing, pool shock is used as a disinfectant to prepare the pool for the winter months.
Also of note, if you were wondering, you cant overshock a pool. The worst that will happen is the water has an abundance of chlorine for a few hours. Once the sun comes out, it will quickly destroy the chlorine and bring the pool back to a level that is safe for swimmers.
How Can I Tell If My Pool Needs Shock
As a rule of thumb, you should shock your pool every week, even if you dont think that it needs it. But, there are several instances when you should certainly shock your pool:
Shock your pool when you open it for the season to kill any bacteria or algae.
Shock your pool after heavy use or a party.
Shock your pool when its extremely hot and sunny. When the weather is too hot bacteria can grow and your chlorine level may lower.
Shock your pool after heavy rain because too much rain can increase pH levels and send contaminants into your pool.
Shock your pool if your smell chlorine or if swimmers eyes become irritated. If this happens it could mean that water has a build-up of chloramines. This is a clear indicator that your pool needs to be shocked.
Shock your pool when you close it. Although youll need to shock it again when you re-open your pool, its always a good idea to close your pool with clean water.
Some people also recommend that you shock your pool anytime the pH level is between 7.2 and 7.4,

A cement pool wont be destroyed by a powdered pool shock, but there is a possibility that there will remain large quantities in some areas.
