Never pour pool shock into the skimmer, pre-dissolve for use in vinyl liner pools. When broadcasting shock across the surface, be mindful of the wind direction. Brush the pool after shocking, and filter the water for at least 8 hours afterward.
Chlorine is a sanitizer, and (unless you use Baquacil products) is necessary for maintaining a clear and healthy pool. Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly.
Before you start pouring shock in the pool, the first step is to brush the sides and floor of your pool to loosen all the algae. Doing this breaks the skin and allows the pool shock to more easily kill the algae. Once you've done this, it is important to make sure you have the proper pH level in your water.
You can add chlorine in tablets and sticks directly to the skimmer, and they slowly dissolve into the pool water. Liquid chlorine comes in gallon containers. You can apply it by pouring the liquid into the skimmer or directly into the pool water.
Let's start with the blanket rule: Don't – not even ever – pour pool shock down into the skimmer. Whether you're using shock granules or shock pods, all types of pool shock should be applied directly to the pool – and when we say “directly to the pool,” we mean like, the big open area where you swim.
So if you've ever wondered if it's OK to put chlorine tablets in the skimmer, the answer is yes. As your pool pump runs, water floats in through your skimmer line, past the pump, into the filter, through the heater, and back into the pool.
They are not chlorine tablets. You have to use liquid chlorine or chlorine tablets to keep your chlorine up. These tablets are just used to keep my pool water crystal clear all summer.
Typically for granular shock, you'll need one pound for every 10,000 to 13,500 gallons of pool water. With over 8 million residential swimming pools across the US ranging from 5 thousand gallons to over 30 thousand gallons, the amount of shock you need to treat a swimming pool isn't a one-size-fits-all answer.
NEVER just throw them into your pool water. This will cause them to dissolve on the floor and it can damage and create a permanent bleach stain to your liner or concrete.
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.
You cannot overshock a swimming pool or add too much. Adding too much shock or overshocking your pool will kill off algae. The negative of adding too much shock is it will upset the chemical balance of your pool.
Neither will chlorination be effective with a diffuser and without a pump. The best thing to do is to apply liquid chlorine in the pool. Then, you have to circulate the pool manually with the use of a telescopic pole or paddle. This will ensure the chlorine disperse well.
Example – A 50,000 litre pool will require up to 200 grams of chlorine and if 5 people use the pool a further 50 grams of chlorine is required = total of 250 grams per day.
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.
It Should Not Be Done Together
This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
After Shocking Your Pool
It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours. It is always best to test first!
If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
Another cause for high alkalinity can be when you shock the pool. While this is performed to quickly rid the pool of pollutants, chlorine-based pool shock is highly alkaline, and can raise the water's total alkalinity level in the process.
To shock your pool, use 2 pounds of shock for every 10,000 gallons of water. This should raise your chlorine levels to 10.0 ppm. Depending on your pool, you can use either Leslie's Power Powder Plus or Leslie's Chlor Brite.
As a general rule of thumb, pH can be adjusted with the following: 1 oz. of pH Increaser (soda ash or sodium carbonate) added to 1,000 gallons will raise pH by 0.1.
While a floater does not distribute chlorine as evenly as an in-line chlorinator, it is still a great form of swimming pool chlorination. Never put chlorine tablets into the skimmer baskets of your pool. Some pool companies will put chlorine tablets directly into the skimmer baskets of the pool.
Not running the pump 24/7 is also a sanitary issue, and is the primary cause of a murky pool. The moment you turn off your water pump, debris, algae and bacteria start to build up, which can eventually lead to cloudy or green water. ... Specifically, we recommend using a Pentair IntelliFlo pump.
