Buy Hot Tub Chlorine and keep your hot tub water clean, clear and safe.
Chlorine is a sanitizing agent, and makes short work of microbiological particles that naturally exist in any water environment, particularly a hot tub. Why are hot tubs at greater risk of these compounds? Because the average hot tub temperature is well over 100 degrees Fahrenheit - it's the perfect incubator for bacteria, algae, mold and mildew. In fact, hot tubs are constantly at an increased risk of these organisms as compared to swimming pools, where the water temperature rarely rises beyond the low to mid 80's.
Hot Tub Chlorine Brands
If you need to buy hot tub chlorine, check out these brands. They're widely considered the industry leaders, have great reputations and in many cases cost less than the inferior products.
Leisure Time Spa 56 Chlorine
Spa 56 granulated chlorine comes in two sizes: A two pound tub and a five pound tub. Obviously the product is the same in both, but you can usually get more bang for your buck by ordering the bigger size (it's the typical "save when you buy in bulk" idea). But considering you'll only be using a few tablespoons per day, even the two pound canister will go a long ways.
I've always had really good and consistent results with Leisure Time Spa 56 products, and almost always choose it over any other brand.
Natural Chemistry Chlorine
This product is only available in two-pound containers, though I've heard rumblings at my local hot tub supply store that it might offer larger capacities in the future. But remember that you should get several months out of a two-pound container, considering you'll only be using a few tablespoons per day.
Natural Chemistry works very quickly, is stable and safe in storage and easy to measure. Though I personally like Leisure Time, Natural Chemistry is a close second. I've used it several times and have no complaints. It's just that Leisure Time leaves the water smelling less like a chemical vat. Not that this product has a strong odor (and trust me, all chlorine will have that distinctive smell), it's just slightly more overpowering than the other.
Nature2 Spa Stick Mineral Sanitizer
Again, I haven't used this product so I'm uncomfortable offering a good or bad recommendation. But I did want you to be aware of it, should it be something you might want to try out.
Buy Hot Tub Chlorine Online And Save
Assuming you don't need it right away, buying chlorine online can save you plenty of money (compared to buying at a local hot tub specialty store, where prices are almost always inflated to cover overhead costs).
Your best bet is Amazon. Not only does the company almost always have the lowest prices, it also offers the safety and satisfaction that's unmatched by most other online retailers. If you'd prefer to purchase your spa and hot tub chemicals offline, I'd recommend finding a specialty hot tub supply store.
