How do you maintain a Bromine hot tub?

Run the filter several hours daily.

A proper maintenance schedule for spas depends largely on how often the spa is being used and by how many people. Follow the basic guidelines below for caring for your brominated spa.

Sanitize

It is important to maintain adequate total bromine residuals. This varies depending on the product you are using.

Brominating Tablets

When starting with a fresh fill, fill up the feeder or floater with Brominating Tablets according to manufacturer's instructions. Shock the spa using Brominating Concentrate or Chlorinating Concentrate according to label instructions to eliminate undesirable compounds and establish a sanitizer residual. Adjust the feed or flow rate for the Brominating Tablets and test frequently for the first week. Shock as needed until the proper bromine residual can be established and maintained for several days.

Brominating Concentrate


  • Spas using Brominating Concentrate should maintain 3 - 6 ppm total bromine residual.

  • When starting with a fresh fill, add 2 tsp. per 400 gallons with the pump running. Test frequently the first week and add Brominating Concentrate as needed to establish and maintain 3 - 6 ppm total bromine residual.

Oxidize

Spas contain a small amount of water relative to pools. Each person who enters the spa has far fewer gallons of water to share than the same number of people in a pool. And each person who enters the spa introduces cosmetics, perspiration, and other undesirable compounds into the water. Because of this, shocking should be frequent.

A shock treatment should be applied following each spa use. If the spa is not being used for a long period of time, shock weekly. Brominating Concentrate, Chlorinating Concentrate, Spa Shock, or Enhanced Shock can be used for maintenance oxidizing. Many spas are equipped with ozonators, which help eliminate some insoluble compounds, but periodic shocking is still necessary.

Add any of these shock products directly to the spa with the pump running. Brush up any undissolved product.

After shocking, do not use the spa until the bromine residual has dropped to 8 ppm or lower.

Balance

Spa water must be balanced to prevent equipment corrosion and surface damage. To balance the spa, perform a complete water analysis and follow ALEX recommendations. Maintain pH between 7.4 - 7.6 at all times. Add balancing products with the aeration off. For help controlling pH, use Spa Sentry, a pH buffer.

Clean

Rinse the cartridge filter off periodically, and chemically clean the cartridge when the spa is drained and cleaned. The following formula is a good rule of thumb for estimating when to drain the spa.

Spa volume / 3 / average daily bather load = number of days between drains

When cleaning the sides of the spa after draining, use a cleaner that has been specifically designed for spa use, such as Off the Wall®.
