The cold water, anything below 65°, has an impact on the ability of the chemicals to dissolve properly. I would recommend using liquid chlorine if you have to shock in lower temperatures. You can dissolve granular shock in warm water. Perhaps it will work if you completely dissolve it before adding it to the pool.
Shocking the pool during the winter months can certainly help to avoid a green swamp-like pool in the spring. It's often recommended. However, poor water balance or improper application can lead to unintended consequences, such as discoloration and damage to pool surfaces.
The best thing about this dry liquid chlorine formula is that it dissolves very rapidly, even in cold water temperatures. We've packaged it in an easy to pour bottle, just walk it around the pool – no need to pre-dissolve.
You may want to shock the pool during winter if: 1. The water temperature is above 60 degrees. 2.
Between these organics and the living contaminants like algae, warm water has a higher chlorine demand than cold water. Chemical reactions generally work faster at higher temperatures. Water chemistry is no different. So chlorine will work better and faster, and as a result, chlorine will also get reduced faster.
Here's a general rule of thumb: For every 10 degrees Fahrenheit above 80 degrees Fahrenheit, twice as much chlorine is needed in the pool to maintain an adequate free-chlorine level. This is more important for spas, which are regularly operated at higher temperatures.
Pools with water that is too warm can be harmful to swimmers in a number of ways dehydration, muscle cramps and overheating of the body are just some of the complications athletes can suffer from when the water is too warm.
It's often recommended to shock your pool once a week. If you don't do it every week, you should at least do it every other week. This is necessary to maintain your pool's water chemistry. If you have a lot of people over in your pool or have a party, you may want to shock your pool more frequently.
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.
The best time of day to shock pool is when the sun is down. So, experts recommend shocking your pool in the evening or at night, to make sure it does its job. Shocking during the day can be ineffective as UV rays from direct sunlight significantly reduce free chlorine levels.
Add the recommended amount of Blue 2000 or Combat 60 (18 ounces per 10,000 gallons of pool water.) Add the recommended winter chemical kit(s) for your pool, keeping in mind 1 bucket will be enough for 10,000 gallons of water. Run the pool filter for 12 hours. Raise the pool's water to the maximum level.
Using a pool cover is one of the simplest but most effective ways to prevent algae from growing during winter. Algae requires sunlight to bloom, and a cover will ensure the pool water remains dark throughout winter. Plus, a pool cover will also prevent other leaves, bugs and debris from getting into your pool.
Add Chlorine to Your Pool to Ensure a Clean Opening
In the fall, make sure to add chlorine and algaecide to your pool for over the winter. Don't add too much chlorine though. If the chlorine level is too high over the winter, you can bleach the liner.
The filtration system cannot operate without the pump running. Remember as we say at PoolSide, clear water doesn't mean good water, but good water will be clear. Depending on the size of your pool, we still recommend you run your pump run at least 4-6 hours a day during the fall and winter months.
If shocking with chlorine pool shock, add it 5-7 days before closing the pool, as very high chlorine levels can disrupt or destroy your winter algaecide or stain and scale chemicals. You can add Chlorine-Free Shock just hours before other pool closing chemicals, and it won't damage your winter pool cover.
Solution. Never close the cover immediately after shocking the pool. It is recommended to wait several hours before closing the cover. Use a test kit to regularly test the pool water.
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
Give the shock a good 12 to 24 hours to work it's magic. If the algae hasn't cleared up after 24-48 hours, clean and brush the pool and add another shock treatment.
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. Only then should you introduce algaecide to get the best results.
It's pretty tough to over-shock your pool; shocking your pool two days in a row with the proper dosage for your pool volume shouldn't be a problem – and in fact, is sometimes even needed to rid your pool of algae and other contaminants.
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.
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.
Night Air is Cooler
Sometime, the air temperature will drop even lower than the pool water. Since the pool water temperature will not change that much within one or two hours, the cooler air makes the water feel warmer than it was previously.
According to the World Health Organization, water temperatures ranging from 78 to 86 degrees Fahrenheit are generally comfortable and safe for those engaging in moderate physical activity in a pool.
