1. Maintain Hot Tub Circulation

One of the most crucial parts of hot tub maintenance is ensuring proper water circulation. Circulation helps keep your water clear by filtering out debris, bacteria, and oils. If the water is left stagnant for too long, it can quickly become cloudy and even harbor bacteria that can be harmful to your health.

How Hot Tub Circulation Works

Water circulation in a hot tub works by pulling water through a filter, which traps any dirt, oils, or debris. Many hot tubs come equipped with an automatic circulation system that runs on a timer, ensuring the water is filtered even when you're not using it.

Automatic vs. Manual Circulation

• Automatic Circulation: Many hot tubs feature a built-in circulation schedule that runs for 15 to 20 minutes once or twice a day. This is enough to ensure that the entire volume of water passes through the filter.
• Manual Circulation: If your hot tub doesn’t have an automatic system, you’ll need to manually turn on the jets or circulation pump for about 15 to 20 minutes, twice a day. This ensures the water stays fresh and filtered.

Pro Tip: Even when your hot tub is in use, circulation is happening. The more frequently you use your spa, the more you’re naturally circulating the water. Just make sure to clean the filters regularly to keep them working efficiently.

Tips for Improving Circulation

• Run the Jets More Often: If you want cleaner water, don’t be afraid to run your hot tub more frequently than the recommended amount. The more circulation, the fewer contaminants build up.
• Use Tennis Balls: After soaking in your hot tub, toss in a couple of tennis balls. The fibers on the tennis ball help absorb oils and lotions that are missed by the filters.
• Schedule During Off-Peak Hours: Running your hot tub during off-peak electricity hours can save you money on your utility bill while keeping your water moving. Plus, it keeps your water clean without breaking the bank.

2. Stick to a Simple Cleaning Schedule

Circulation alone won’t keep your hot tub spotless—you also need to establish a consistent cleaning schedule. Cleaning your hot tub ensures that no dirt, oils, or bacteria have the chance to build up and clog the system or damage the shell.

Weekly Cleaning Tasks

To keep your hot tub in top shape, perform these weekly cleaning tasks:

1. Wipe Down the Shell: Use a sponge and a solution of white vinegar or a gentle hot tub cleaner to scrub the waterline and seats. This helps remove oils and dirt that can accumulate, especially if your hot tub is outdoors.
2. Remove Debris: If your hot tub is located outdoors, keep an eye out for leaves, dirt, and bugs that may fall into the water. Use a net or skimmer to remove them before they clog the filter.
3. Rinse Filters: Give your filters a quick rinse with warm water or a garden hose to remove debris. Clean filters ensure proper water circulation and help prevent cloudy water.

Monthly Deep Cleaning

Every 3 to 4 months, your hot tub needs a thorough cleaning. Over time, contaminants like oils, lotions, and body care products build up, and regular cleaning becomes less effective. Here’s a step-by-step guide to deep cleaning your hot tub:

1. Drain the Water: Completely drain your hot tub to remove any built-up contaminants.
2. Clean the Plumbing: Add a specialized jet cleaner or pipe cleaner before draining to remove any residue that’s accumulated in the plumbing.
3. Scrub the Shell: Once the water is drained, scrub the interior of the hot tub with a non-abrasive cleaner to remove any residue, scum, or stains that may have formed over time.
4. Refill and Test the Water: Once your tub is thoroughly cleaned, refill it with fresh water. Before you use it, make sure to balance the water chemistry (more on this in the next section).

Pro Tip: Set a timer when refilling your hot tub to avoid messy and costly overflows. This is especially important if you're multitasking or have a lot on your mind.

Hot Tub Filter Maintenance

Your filters do a lot of heavy lifting when it comes to keeping your water clean, so it’s important to clean them regularly. Here are three ways to keep your filters working effectively:

1. Rinse Weekly: Rinse your filters with a garden hose or under warm water to remove debris.
2. Spray Every Few Weeks: Spray your filters with a dedicated hot tub filter cleaner every few weeks to remove oils and dirt that accumulate over time.
3. Soak Monthly: Soak your filters in a chemical filter cleaner once a month to give them a deep clean. This helps remove buildup that rinsing and spraying can’t handle and extends the life of your filters.

When your filters become too dirty to clean effectively, it’s time to replace them. This is typically every 12-18 months, depending on use.

3. Balance Your Hot Tub Water Chemistry

One of the most critical aspects of hot tub maintenance is balancing your water chemistry. Poorly balanced water can lead to a range of issues, including skin irritation, corrosion of hot tub components, and cloudy water. Learning how to properly manage your water chemistry will save you time, money, and frustration in the long run.

Essential Hot Tub Chemicals

Here are the chemicals you should always have on hand for your hot tub:

1. pH Increaser and pH Decreaser: The pH level of your hot tub water should be between 7.4 and 7.6. Anything below 7.4 is too acidic and can corrode your equipment, while anything above 7.6 is too basic, leading to cloudy water and reduced sanitizer effectiveness.
2. Alkalinity Increaser: Alkalinity stabilizes your pH levels. Aim for a level of 100 to 150 parts per million (ppm) to prevent large fluctuations in pH.
3. Sanitizer (Chlorine or Bromine): These chemicals kill bacteria and other contaminants in your water. Chlorine is the most commonly used sanitizer, but bromine is a good alternative for those with sensitive skin.
4. Shock (Non-Chlorine or Dichlor): Shock your hot tub once a week to oxidize contaminants and boost your sanitizer’s effectiveness.
5. Defoamer: Foam can develop in hot tubs from oils, lotions, and soaps. A defoamer quickly eliminates foam and restores the water’s clarity.

Testing and Adjusting Your Water Chemistry

To keep your hot tub’s water clean and safe, it’s important to test it regularly. You should test your water at least once a week, or more often if the tub is used frequently.

1. pH: Use test strips or a liquid test kit to check the pH of your water. If the pH is too low, add a pH increaser. If it’s too high, add a pH decreaser.
2. Alkalinity: Test the alkalinity levels and adjust as necessary. Low alkalinity can cause rapid changes in pH, while high alkalinity can lead to scaling on your hot tub’s surface.
3. Sanitizer: Add the correct amount of chlorine or bromine according to the product’s instructions, and test to ensure levels are within the safe range.

Pro Tip: Turn off your hot tub’s air valves while adding chemicals. This helps the chemicals circulate more efficiently and allows them to mix thoroughly with the water.

Common Water Chemistry Issues

Even with regular testing, you might run into a few common water chemistry issues. Here’s how to troubleshoot them:

• Cloudy Water: Often caused by high pH or sanitizer levels that are too low. Adjust your pH and shock the water to clear it up.
• Foam: Foam can occur when there’s too much soap, oils, or lotions in the water. Use a defoamer and rinse off before getting into the hot tub to prevent foam buildup.
• Strong Chlorine Smell: A strong chlorine smell often indicates there are too many chloramines (a byproduct of chlorine that hasn’t been broken down). Shock the water to get rid of the smell.

4. Prepare Your Hot Tub for All Seasons

Your hot tub will need different care depending on the season, especially if it’s located outdoors. The transition from warm to cold weather can affect the performance of your spa, so it’s important to make sure your hot tub is ready for the changing seasons.

Spring and Summer Hot Tub Maintenance

Warmer weather can cause issues like algae growth and higher evaporation rates, so here’s how to prepare for the spring and summer months:

• Shock the Water: At the start of the season, shock your hot tub to get rid of any lingering bacteria or algae from the winter months.
• Remove Debris: Spring can bring wind and rain that deposit debris into your hot tub. Regularly check for leaves, dirt, and bugs, and remove them to keep the water clear.
• Balance the Water: Before diving into summer hot tubbing, make sure the water chemistry is balanced to prevent issues like cloudy water or algae growth.

Fall and Winter Hot Tub Maintenance

Cold weather brings a new set of challenges for hot tub owners. Here’s how to prepare for fall and winter:

• Add Water: Water evaporates faster in cold weather, so make sure your hot tub is topped off to the correct level.
• Lower the Thermostat: If you’re not using your hot tub as frequently in the winter, lower the thermostat by about 10 degrees to save on energy while keeping the water from freezing.
• Keep the Pump Running: When temperatures drop below freezing, make sure your hot tub’s pump and heater are running to prevent the water from freezing. If the water freezes, it can damage the pipes and pump.

Pro Tip: If you’re not planning to use your hot tub in the winter, consider winterizing it by draining the water and blowing out the pipes to prevent freezing.
