    This is the best and most straight forward video I’ve found about pool shocking. Although, I don’t agree with everything, for example, I live in Tampa bay, the US capital of lightning storms. If I followed rules 5 (at 3:15, shock after a heavy rain) and 6 (at 3:26, shock after extremely sunny or hot weather), I would have to shock the pool almost every day starting from mid Spring to the end of Fall, lol.

      If you buy the bulk bucket it should tell you what % it is. Either way, it should tell you how many oz's per thousands of gallons. usually its going to be anywhere between 1-2 lbs. I service pools and I usually shock weekly during the summer, but the amount of shock also varies depending on pool usage and size. Heavily used pools get more than recommended dosage.

    Hello Swim University,
    I have a SWG Intex pool, 14,364 gallons. I have a SWG that came with the pool(it produces 11g of chlorine/hr) and it has a "boost" mode where it simply runs the chlorinator for 36, 48, or 60 hours. My question is this, is running the boost mode weekly going to obtain a similar result as the traditional shocking method(of putting a large amount of chlorine into the pool by adding bags of shock)? If so, then I have a follow up question. I would like to use this boost mode to shock my pool if possible(since it wouldn't require me buying bags of chlorine) but it seems impractical to boost my chlorinator which takes 36 hours to do(and me not being able to use it due to elevated ppm levels), and THEN once the chlorinator turns off to wait even more time for my free chlorine numbers to go back down to 3ppm. I would lose almost 2 days of swimming every week, unless i'm calculating something wrong. What would you do if you were me and wanted to use your pool almost daily?
    thanks.

      No you don’t have to. Get a water testing kit. If you just filled up your pool with tap water it will last a solid week. The best thing anyone ever told me was buy a chlorinator. Since I’ve installed I dont have to worry about chlorine or being clear. Little baking soda or soda ash. 3 red solo cups every 2-3 week. Half bottle of Algecide every 3 weeks. Also look for filter socks. If keeps the sand clean that filters your pool. Once a week don’t forget to backwash for 30 seconds and rinse for 15 seconds. That basically is like scraping the head off of the top of a Guinness. Takes all that nasty sand and crap out!
      Good luck! Oh and remember swim as much as possible. Walk in circles or around perimeter of pool. It’s stirs up everything chemical wise that you put in and stuff that needs to make it to the skimmer. Go have fun!

    I have an in-ground salt water pool, and I know that the iChlor system will produce chlorine on it's own through electrolysis so I should not need to add chlorine to the pool. However, in the winter the water gets too cold for the iChlor to work. Is it recommended to shock the pool regularly with chlorinated shock during the winter months? I watched my pool go from crystal clear to dark green in the matter of a few days as soon as the indicator light on the iChlor that it was no longer producing chlorine.

    Hi I have a small pool 12x 10 I just filled it with clean water should I shock it I also bought the clear balance. I’m so lost

    • @jamusmorrison3073

      If filled with tap water you will start to see that it’s lost it’s chlorine. You need to shock it liquid or powder. Then put in that clear balance. Read the bottle. Do both after the direct sunlight is off the pool. Shock one night and used clear balance the next.
      Good luck.

      Also remember to backwash and rinse. Make sure to turn off between each cycle. You only have to backwash and rinse 15-20 seconds.

    I can't find chlorine tablets anywhere!! But shock is readily available (and not at a sky high price either). Possible to just add less pool shock granules on a daily basis rather than a floating chlorine tablet holder? Any advice in this regard?

    We have a 10ft above ground pool. I have been using 20g multifunctional chlorine tablets in a floating dispenser in it, and have tested the levels every day, most to all levels are ok, but the cyanuric acid level is high. We have tried draining some water out and replacing it but it’s still high. Someone has suggested using chlorine shock in. Will this help? If so what is the best thing to get (we are in the UK), and how much do we use? It’s 10ft diameter, 2.5ft deep and holds around 1250 gallons of water.

    • @nuntana2
      @nuntana2 4 роки тому

      Possibly using too many tabs. Only way to lower cya level is dilution but it’s not linear. Keep vac’ing to waste and give it long backwashes. Consider using non-stabilised tabs for a bit.

      It's very common for shock to turn the water cloudy. It killed off contaminants. Clean and run your filter for 24 hours. You could also use a flocculant to remove the cloudy, dead particles (if you can vacuum on the waste setting)

    Is it possible to shock too much?

    • @SwimUniversity
      @SwimUniversity  4 роки тому +3

      Always follow the directions on your pool shock, but in general: no, you can't. However, adding shock directly to the pool water (especially if you have a vinyl liner) can be can cause issues so be sure to pre-dissolve it if the directions say to do that.

      Too much of anything is bad, overly using shock can increase chlorine to harmful levels and even make water cloudy (thanks to added calcium)

      Avoid using ground sourced water for pools unless you have a filter. TDS will be high and filtration will struggle.

    Someone told me a photometer also measures total chlorine which test strips cannot do. If your total chlorine is high, then your free chlorine cant work and means your pool is full of dead chlorine. So are they saying the test strips are useless because you can’t test total chlorine?
    I always thought that as long as test strips says your free chlorine is at 3ppm then that means it’s above total chlorine and everything is ok?
    OR.. Is it in fact possible for the test strips to read ok at 3ppm free chlorine but total chlorine can still be higher rendering the 3ppm free chlorine useless?

    • @nuntana2
      @nuntana2 4 роки тому

      Correct. They don’t show total/chloramines. Test strips are ok as a general indicator but are not great for pools.
