Which Chemicals Do You Need To Open A New Pool? It’s time to get your pool ready for swimming season and that means adding a dose of pool opening chemicals and adding the right chemicals now means preventing algae and cloudy pool water later.
Luckily, all the chemicals you need to open your pool in the spring are the same ones you’ll need for regular pool maintenance
throughout the year.
So, here’s what you need to know about pool opening chemicals, and how to add them.
Check it out.
Before you add any chemicals to your pool, make sure that you’ve completed these pool opening steps.
One, remove the cover, drain plugs, winterization plugs, and ice compensators.
Two, inspect the pool filter system, pumps, return line, and other areas for damage.
Three, refill your pool with water so that the water level is midway up the skimmer.
Four, clean up leaves and debris with a skimmer net.
And five, turn on the filter and let it run for 12 to 24 hours to circulate the water.
Now, if you need any help with these steps before starting to add chemicals, be sure to check out our step-by-step pool opening videos.
Now it’s time to test your water.
You won’t know what chemicals to add if you don’t know what your water chemistry looks like.
Test strips are a quick and easy way to test your levels, but you may wanna run a water sample over to your local pool supply store.
This will give you a more accurate baseline and they can test for other things like metals in your water.
It’s a totally free, easy-to-use guide to help you keep your pool clean and clear.
Now when you test your water, you’ll wanna test for the following levels: pH, which should be between 7.4 to 7.6 with 7.5 being ideal; total alkalinity, which should be between 100 and 150 parts per million with 125 parts per million being ideal; free available chlorine, which should be between one to three parts per million with three parts per million being ideal; cyanuric acid, or CYA, which should be between 30 and 50 parts per million with 50 parts per million being ideal; and your calcium hardness, which should be between 175 and 225 parts per million for vinyl liners or fiberglass pools, or 200 and 275 parts per million for concrete or plaster pools.
Once you know what needs adjusting, it’s time to start balancing your water with the right chemicals.
Now you may have seen pool opening or pool start-up chemical kits.
Depending on your water test results, you may not need everything that kit comes with, such as algaecide or a metal sequestering.
So, regardless of whether or not you buy a startup kit, you’ll wanna have the following chemicals for opening your pool and maintaining your pool throughout the season: alkalinity increaser, pH increaser, pH decreaser, cyanuric acid, also known as CYA or chlorine stabilizer, pool shock, chlorine pucks or the sanitizer of your choice, and calcium hardness increaser.
And as always, when adding chemicals be sure to have protective gear like gloves and goggles.
Remember, safety first.
Now it’s time to start balancing your water.
Here’s the order we recommend adjusting your water chemistry.
First, you wanna adjust your alkalinity.
Alkalinity helps buffer and prevent fluctuations with pH.
So, we want to adjust these levels first.
If you need to raise your alkalinity, you can use an alkalinity increaser or baking soda.
If you add an alkalinity increaser, you may also raise your pH.
Next, you want to adjust your pH if necessary.
You can lower your pH with a pH decreaser, or if you need to raise your pH you can use a pH increaser or soda ash.
After you adjust your pH, adjust your cyanuric acid, or CYA levels, if needed.
This helps to stabilize the sanitizer you’ll add later to your pool.
Wait an hour or so with the filter system running and then retest and adjust these levels before adding any more chemicals.
Next, we’re gonna be shocking the pool.
Now, before you shock, give your pool a good brushing.
If your pool water is cloudy, you’ll wanna double shock your pool and that means adding two pounds of chlorine shock for every 10,000 gallons of water.
If you open up your pool to really green water, you should check out other videos on how to get rid of algae.
Let the shock work overnight with your filter system running.
After your chlorine level has come down to the proper range, add your chlorine or sanitizer.
We recommend adding chlorine pucks or tablets to a chlorinator or directly to your skimmer.
Finally, adjust your calcium hardness levels.
Low levels of calcium hardness can do damage in the long run, like eroding parts in your pool.
So, you can actually wait until the water is sanitized and balanced before adjusting your calcium hardness.
Those are the chemicals that you need to open your swimming pool.
