Not Brushing Your Pool

How To Shock A Pool The Right Way

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.

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.

Pool shock can raise the chlorine level of a pool very quickly so make sure that you are careful when adding it to a pools water.

  • What Should I Look For in the Ingredients of Pool Shock?
  • Type Of Active Ingredient

    Next, you need to think about the key active ingredient in each product. 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.

    Why Shock Your Pool

    What Type Of Pool Shock Should I Use So It Doesn’t Break My Wallet

    Over time, as chlorine works to destroy contaminants, the combined chlorine level rises and this is far weaker as a pool water disinfectant.

    By shocking your pool, you replenish your chlorine level and oxidize chloramines , which are a gaseous irritant that are hazardous for human consumption.

    Your swimming pool may need to be shocked if any of the following scenarios have occurred:

  • Theres an increase in pollutants: Pools are subjected to many changes in water chemistry. This contamination can be from rainfall, outside temperature shifts, backyard debris, and organic matter left behind after heavy pool use.
  • Algae growth in the pool: Algae blooms are usually controlled by applying an algaecide to the pool. But when you need to eradicate it, a shockor triple shockwill do just that, clearing up the water at the same time.
  • Theres a buildup of chloramine: Chloramines are what we all know as that pungent dose of pool smell. Theyre a gas that forms as a result of used up chlorine, and an indication theres not enough chlorine in the water. Chloramines irritate your eyes, nasal passage, lungs, and skin. If the pool has a very strong chlorine smell to it, you know its time to shock.

    Make A Shocking Solution

    If using granular shock, youll need a 5 gallon bucket for this part.

    Start by filling the bucket with water , and then adding in 1 bag of shock. Always add the shock to the water not the other way around.

    Using a wooden stir stick, mix the solution until the shock is fully dissolved. This will help disperse it evenly in the pool and save your liner or pool finish from being damaged.

    If you are using liquid shock, you can add this directly to the pool water

    Hth 42033 Super 3 Chlorinating Tablets

    This is a different kind of pool shock from the liquid and powdered ones weve discussed. This one comes in circular tablets that you place in a pool skimmer, feeder, or floater and it does the job.

    The HTH tablets are designed to kill and protect your pool from bacteria and algae. What I find fascinating about this product is that it contains some sort of sun-protecting element that helps extend the lifespan of chlorine.

    The manufacturer recommends you use one table a week. A single tablet is enough to keep 10,000 gallons of water clean and clear.

    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.

    Best Pool Chemical Reviews: 20 Top Picks of 2020

    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.

    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,
