NOTICE: The Texas weather emergency in February, in addition to the ongoing demand increase for pool products from the Covid pandemic, have caused industry-wide shortages on many products that most vendors expect to last late into 2021/early 2022. We're allowing items to be purchased so that customers who choose to wait will have their order shipped when product arrives. Many times there are long shipping delays on the few products we do have in stock. Please contact us to ask about availability. Live Chat and email are the best. Please keep trying back via chat and email as we can't answer them as fast as they come in but we are here, so keep trying! We're currently 20+ days behind on returning email (email is the best way to get a reply when all chat associates are busy).

What Hot Tub Chemicals Do You Need?
While it’s recommended you change your hot tub water every three months or so, and give it a good cleaning every so often, it’s still essential to sanitize the water in between so it doesn’t become a breeding ground for unwanted bacteria.
 
Test the Water
To keep your hot tub water clean, you first need to know what chemicals your hot tub water needs; this is where a test kit comes in handy. Test strips are one of the easiest ways to test and balance your water accordingly. It’s recommended that you test your hot tub water at least once a week.
 
Sanitizer
One of the most important hot tub chemicals you need to use is a sanitizer. Two of the most popular sanitizer options are bromine and chlorine. Chlorine is cost-effective and easy to manage, but bromine tends to be gentler on the skin, lasts longer, and has a lower pH than chlorine, making the task of keeping your spa water balanced even easier.
 
Balancers
Balancers are used to adjust the pH and the alkalinity of your pool water. They also help prevent stains and scale build-up in your spa. Pool Supply Unlimited has spa balancers from leading spa chemical companies like Leisure Time and SeaKlear.
 
Shocks
Shock is a spa chemical used to break down waste and contaminants that cause cloudy, foamy water and bad odors. Shock should be added to a pool once a week as part of your regular hot tub maintenance routine, when the hot tub has not been used for an extended period or when the free chlorine level is lower than the total chlorine level.
 
Algaecides/Phosphate Removers
When spas and hot tubs in outdoor environments are exposed to elements like rain, water, and other natural materials, it can cause algae and phosphates to be present in your hot tub. That’s why as part of your spa maintenance system, we recommend using an algaecide and phosphate remover. We carry a great selection from Leisure Time, Easy Care, and ClearView.
 
Whether you need a specific spa chemical or want to shop hot tub chemical kits to make your hot tub maintenance even easier, Pool Supply Unlimited has the spa chemicals you need to keep your hot tub water its cleanest. Shop today!
