Liquid Chlorine Pool Shock (Case - 4 Gallons) - 12.5% Sodium Hypochlorite

Let's not beat around the bush ... at $50-70 for 4 gallons this is a clear case of taking advantage of the chlorine shortage to make a quick buck. :)However, I can confirm that the product is real and of the expected level of potency, as measured with test strips before and after application to a residential pool.Chlorine at this level of concentration has a shelf life of only a few months, so don't be a fool and order way more than you can use immediately (as you will end up with only salt water - while prolonging the shortage for everyone else).

Works as it should! Bottles are full and get the job done. Only reason not 5 stars on valid for money is because I bought this way cheaper last year, but everyone’s price gouging this year on chlorine.

I got this because typical powdered shocks don't dissolve well in cold water, so they don't bring the chlorine level up fast enough in the spring. This worked really well, I think because it has a higher concentration of chlorine than some other products.
