Liquid chlorine %

Read the labels, know what you’re buying. Liquid chlorine strengths vary.

The most popular way to open a swimming pool in the spring is to add a large dose of liquid chlorine. Some people also use it as a weekly shock or as a quick fix for a green or cloudy pool. What I want you to be aware of as a consumer is that there are different strengths of liquid chlorine available for purchase. In my store I carry the strongest, 12.5% sodium hypochlorite. I have found that most “big box” swimming pool stores and hardware stores carry 10% sodium hypochlorite solution but don’t advertise it that way. Unfortunately when it comes to swimming pool chemicals, an uninformed consumer will usually buy on cost alone. If you don’t mind the weaker chlorine, go ahead and buy it. It won’t hurt anything; you’ll just need more of it. I want you to be aware that there is a difference, and one store may sell the 10% solution for a few cents cheaper or for the same price as the 12.5% solution. Now that you’re aware of this you can be sure that you’re getting what you paid for. Purchasing liquid chlorine, like most other swimming pool chemicals, comes down to active ingredients. Chlorine at a “big box” pool store may be 25 cents cheaper then at a local swimming pool dealer but it may not be as strong. That 1 gallon jug of algaecide you bought at the hardware store for half the price of a quart from the local pool dealer may seem like a great deal, until you read the ingredients. Now you need 4 gallons to get the same amount of active ingredients that are in the quart. Read the labels on all products and make sure you know what you’re buying. This will make your pool season run smoother and cheaper.

  1. I have a 21′ aboveground pool and everytime I add liquid chlorine to my pool the PH seems to rise. Does liquid chorine have a high PH?

    • liquid chlorine has a PH value of 13-14 and in a high dosage will raise the PH level of a swimming pool.
