About This Product

About This Item The amazing all-in-1 weekly formula in HTH Shock Ultra increases chlorine levels, kills and prevents bacteria and algae, reduces eye and skin irritation, prevents stains from metals, prevents scale, improves filtration and softens water—all with results in 24 hours! Traditional chlorine products contain cyanuric acid (CYA). When too much CYA builds up, it can cause overstabilization or chlorine lock, cloud your water and cause algae growth. The fast-acting, fast-dissolving Cal Hypo based formula in HTH Shock Ultra provides chlorination without adding extra CYA for a beautiful sparkle all season. It’s ideal for all pool surfaces and won't fade your liner. How To Use HTH Shock Ultra Follow the on-pack instructions according to your pool size to add HTH Shock Ultra directly to swimming pool water or skimmer. The built-in Visible Blue Action lets you know it’s working! For best results, apply HTH Shock Ultra as part of your weekly pool care routine to keep free available chlorine levels between 1 and 4ppm. About HTH Pool Care We know that maintaining your pool water can be a lot of work. That’s why we're here every step of the way, helping you clear the uncertainty from pool care.

Excellent for urgent and maintenance pool cleaning
[This review was collected as part of a promotion.] I have had more green algae this year than any other year in my pool. I think it’s because it has been so rainy here in southern Alabama. I lined this shock because it worked fast. I put it in the pool and manually vacuumed the dead algae out of the pool the next day. In the past I had only been putting a shock in the pool when I noticed algae, but now I have started using this monthly for maintenance (especially during high utilization seasons). I have found that it’s much easier for me to prevent the algae than to kill it and then vacuum it each time.

    Fantastic product
    [This review was collected as part of a promotion.] I really like HTH® Ultimate Shock! Treatment. 1 pound pack covers 13.500 gallons. I have a 30,000 gallon pool plus my hot tub and only used 2:packs of this aqua blue colored shock last night 8:30 pm and woke up at 6 am my pool is looking clean and clear. The little bit of Algae has been wiped out! I will definitely purchase my new found pool shock. Great quality for great value. Thank you so much

          Amazing!
          [This review was collected as part of a promotion.] We have tried everything to get our pool clear. Nothing worked until we tried this shock. Not even 24 hours later our pool was clear and the water looked amazing. I love how the shock turns blue so you know it's working. Being a 7 in 1, it covers everything including algae. I'm so excited to finally get in and swim.

Treatment, 6 x 1 lb keeps my pool looking as clear and blue as the ocean before i started using the shock treatment my pool would always turn green after a few days but one dose of shock and the problem has been solved and it lasts a few months before i have to redo it

                  Great treatment
                  [This review was collected as part of a promotion.] I was very excited to try this shock because I have tried a few different brands that don’t work very well. This particular one works amazingly. It only takes one treatment to make the levels reach normal and doesn’t leave the water over done with chemicals
