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 want to 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, by the way, if you're looking for help taking care of your pool throughout the season check out our free pool care cheat sheet at swimuniversity.com cheat sheet, 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 want to 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, cyanaric, acid or cya, which should be between 30 and 50 parts per million, with 50 parts per million being ideal and your calcium harness, 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 startup 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 want to have the following chemicals for opening your pool and maintaining your pool throughout the season. Alkalinity increaser ph increaser, ph decreaser, cyanoarc 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 want to 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 synaric 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 re-test and adjust these levels before adding any more chemicals. Next, we're going to be shocking. The pool now before you shock give your pool a good brushing if your pool water is cloudy. You'll want to 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 our 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.

    First time pool owner and I screwed up opening my pool. I bought a start up kit and followed their directions. My water was not balanced before I shocked it. How do I start over?

  10. Avataaar/Circle Created with python_avatars MrBratfox says:

    First timer here.. just about to start up an 10ft Intex easy set up pool. There are absolutely no chemicals to be found in our area and price online are horrid lol. What household items (bleach, baking soda etc.) can I use to start up the pool and how to do it please? I have no idea about any of this…so lost! Lol

  11. Avataaar/Circle Created with python_avatars Michael Mutti says:

    Followed this last year, worked perfectly. I never had the order of chemicals correct causing a lot of extra work

  12. Avataaar/Circle Created with python_avatars r0bert0e says:

    I just had my pool replastered (13K gallons). I am in the process of balancing out the TA and pH. Once that is done I plan on adding a bottle of conditioner (CYA). Question, once this is all done, can I shock the pool to get the chlorine level up? Or should I just add chlorine tablets to the skimmer?

  13. Avataaar/Circle Created with python_avatars HelSan74 says:

    For a new 12feetx40in frame pool set first time use. Do I need to use all the chemicals? Thanks

  14. Avataaar/Circle Created with python_avatars Magical Melody says:

    Quest. Why do all the shock bags say that one bag is for 10,000 gallons if you need 2 per every 10,000? If that’s the case that’s mis advertising their product and I’ve been doing it all wrong this whole time. In my first pool, that was 7000 gallons so I just one. Now in my 22foot pool I’ve been using 2, but technically I need 2 and a half to 3 sense my pool is more than 10,000 gallons, like at around 12,000 I think.

  15. Avataaar/Circle Created with python_avatars Rick Kanski says:

    Darn i didn't know you are suppose to take the cover off first…i been throwing all the chemicals on the top of the cover…no wonder they are not working LOL Service area Orleans??

    I have an above ground pool with a pool fence installed. What’s the easiest way to remove the winter cover off. Please help.

    You need to do a video for chemicals for easy set pools and opening chemicals easy set pools. I have yet to find a useful video for this exact thing

    So I am a new Pool owner and had just opened up my pool 2 weeks ago. I still haven’t manage to get pool clear. It’s blue but cloudy I can see bottom of Pool in shallow end. pH is at 7.2 and Total alkalinity was at a 92. I was gonna try to add baking soda to it but wasn’t to sure how much add… Those were the results I got from the pool and spa shop they also told me I needed to add 30 bags of shock to pool but I think it’s a little excessive to add that much. So I added 6 bags of shock and 6 bottles or liquid chlorine. Been skimming pools, brushing and cleaning baskets daily. Thoughts?

  20. Avataaar/Circle Created with python_avatars Amber Ebbs says:

    We opened our pool a week ago and our Chlorine levels are not showing up on test for chlorine.We have put chlorine tablets into the pool. What is our next step to get in a good chlorine level?

  21. Avataaar/Circle Created with python_avatars Dena Rasmussen says:

    Your information is AWESOME!

  23. Avataaar/Circle Created with python_avatars Zach Ostroff says:

    Hey I'm thinking about starting a pool cleaning business over the summer. I'd plan to have a job set up as a backup, but do you think the overhead costs will be super high that it wouldn't be worth it?? I've been watching these videos and really think I could handle the cleaning and maintenance aspects, but don't want to invest so much and come in way too far over my head. Thanks for the help! Are you in Barrhaven ?

  24. Avataaar/Circle Created with python_avatars swimming pool malayalam says:

    Thank you Are you in Nepean ?

  25. Avataaar/Circle Created with python_avatars Tyler J. Spry says:

    Can you take off the winter cover and put on the solar cover and open later? It’s currently highs in the mid 40s- lower 50s and lows in the mid 30s. Everything is thawed out and had a bunch of rain so the pool filled back up. I want to take the winter cover off but not necessarily get the filter out and running yet. Thoughts?

    I learn something each and every time I watch SU's videos! Thanks SU Team!
