Description

SPA AND HOT TUB USE: Each level teaspoon (0.17 oz.) of this product will provide approximately 1.4 ppm available chlorine in 500 gallons of water. Using an appropriate test kit, test and adjust the water to the following values: pH 7.2-7.8, total alkalinity 60-100 ppm, calcium hardness 200 ppm minimum. Maintain these conditions for proper spa and hot tub operation by frequent testing with a test kit. Do not allow cyanuric acid level to exceed 150 ppm. It is recommended that spas and hot tubs be drained every 30-90 days. More often under heavy use. Consult manufacturer’s recommendations concerning the compatibility of chlorine sanitizers with their equipment. Some oils, lotions, fragrances and cleaners may cause foaming or cloudy water and may react with chlorine sanitizers to reduce their efficacy. START-UP (FRESHLY FILLED): 1. Turn on the circulation system and ensure that it is working properly. 2. Add 6 teaspoons of this product for each 500 gallons of water. Check the free available chlorine (FAC) and, if below 4-5 ppm, repeat as needed. Re-entry into treated spas is prohibited above levels of 3 ppm of chlorine.

    • If you have a small spa that is covered most of the time you don't need this much, read why...
Size: 5-Pounds Style: Chlorine Granules
I wish I knew this from the start, but all all solid/powdered chlorine has cyanuric acid (CYA), which is chlorine stabilizer, so it doesn't lose it's germ killing ability in the sunlight or heat. The thing is, too much of it will kill the chlorines' ability to even kill germs, there is actually a legal public pool limit of 100 ppm. If you only use powdered/solid chlorine in your spa CYA levels will build up and blow past this level in a couple of months and you'll end up with cloudy water from breeding germs and can get people sick. Especially if your spa isn't exposed to direct sunlight much, you don't need or want much CYA. So unless you want to drain and refill your tub every couple of months and waste electricity heating the water back up and money on more chemicals too, the key is to use this stuff for the first week or so after a fill, use test strips to get CYA to 30-50 ppm and ***then switch to liquid pool chlorine*** which doesn't have stabilizer and is cheap, then just add a tiny bit of this once a month to keep your CYA in the 30-50ppm range. You can always web search "spa water chemistry" and learn more, but that is the gist of how chlorine works. Then your spa water can easily go a full 6 months at a time without draining and refilling due to high CYA and cloudy water! Hope this has been helpful and maybe convince you buy a smaller container of this and then go with mainly liquid pool chlorine, good luck! ... show more

    • The how to open the bucket directions.
Size: 5-Pounds Style: Chlorine Granules
Really tricky to figure out how to open. But I now know how. See below. Company should send me a free bucket and a company polo shirt for doing the helpful instructions below. Top fine print embossing on the lid says to push the tab "back." This is not at all easy to read or even see, and it is not at all helpful. What does "back" mean anyway. The embossing department could have spared one other tiny arrow point out from the center toward the lip. It is a safety latch, so for the sake of safety of children or spills do not remove it or defeat it. Chemically blind eyes will have an even harder time seeing what the embossing does and does not say. Red latch is curved on the inside for a thumb to be able to push it toward the outside of the bucket. Put your thumb on the red latch part. Place your fingers of same hand on the outside opposite the latch where your thumb is. Squeeze the thumb toward your fingers, effectively your are pinching your fingers and thumb together. Have the bucket resting on a clear flat surface. Have someone with strong large hands hold the bucket. You do not want to fumble and spill or shake the the chemicals into your face as you get it open. Place your other hand on the opposite side of the lid. Rotate the top counter-clockwise, just like opening a jar. When the lid is put back on you will hear the light sound of clicking, if the latch is properly seating. It may take a wiggle to set it so functions as a safety. Future openings are going to be much easier. ... show more
