Hot Tub Chemical Tutorial - Basic Maintenance

Basic & easy water chemistry. Understanding the WHY to know the HOW.

TEST STRIPS - INSTA-TEST 3

The WHY:  Insta-Test is a quick and straightforward way to monitor the levels of Alkalinity (TA+), pH (pH+), & Chlorine (FCL) or Bromine (Br) in the water.

The HOW:  Dip the strip into the water and compare the colours to the chart located on the bottle. If you have recently added chemicals, run the pumps & wait a minimum of 2 hours before testing the water. Testing too quickly will result in an inaccurate reading.


ALKALINITY - DAZZLE BALANCE TA+ (Total Alkalinity)

The WHY:  TA Stands for Total Alkalinity & helps to stabilize the pH levels in the water. If Alkalinity is low, pH will burn off faster. Increase/balance your Alkalinity levels 1st, and pH levels 2nd *   *See Note On pH+*

The HOW:  The goal is between 80-120ppm, which gives you a range of 40ppm to have an acceptable level. Focus less on aiming for perfection. Instead, try to avoid faded or vibrant colours to maintain your Alkalinity levels. If the test strip reads faded 0-40ppm, add TA+ to the water with running jets. Wait a minimum of 2 hours to re-test. Repeat this until you have the ideal colour range.  It's okay to bring TA+ up slowly, over several hours or a few days, to ensure you don't overdo it.  For maintenance, check levels once a week and add as needed.  If your Alkalinity levels read too vibrant 180-240ppm and you need to bring them down, you can use a pH down (which will also reduce your pH)

HOW MUCH TO ADD:

*These are estimated values to give you an idea of how much to put in your hot tub. Adding small increments & being consistent is more important than being exact*

Small Tub (68”-76”) 1000L

Med Tub (78”-86”) 1500L

Large Tub (88” – 96”) 2000L


20g or 2 Capfuls = 10ppm/1000L

30g or 3 Capfuls = 10ppm/1500L

40g or 4 Capfuls = 10ppm/2000L


pH       DAZZLE BALANCE pH+ (up/ DAZZLE BALANCE pH- (down)

The WHY: pH signifies the acidity/alkaline level in the water. Your sanitiser (Chlorine/Bromine) is an acidic product that will continue to drive your pH levels down. When pH is low, the water is more acidic. If you don't continually bring these levels back up, the water's acidity will break down plastics/metal components in the hot tub at an accelerated rate. You will need pH+ to increase the levels.

Sometimes pH Levels are high right out of the gate (Fresh Tap or Well Water), meaning the water is more alkaline; this can result in skin irritations during soaks. You will need pH- to decrease the levels. 

The HOW: The goal is between 7.2 & 7.8, giving you a range of 0.40 to have an acceptable level. Focus less on aiming for perfection; instead, try to avoid the faded or vibrant colours to maintain your pH levels. If the test strip reads faded 6.2 – 6.8, add pH+ to the water with running jets. Wait a minimum of 2 hours to re-test with a strip. Repeat this until you are in the ideal colour range.  It's okay to bring pH+ up slowly, over several hours or a few days, to ensure you don't go over.  For maintenance, check levels once a week and add as needed.  If your pH levels read too vibrant 8.4-9.0 and you need to bring them down, you can use a pH- (down) 

NOTE * If you need to bring your pH levels DOWN, do this before increasing your Alkalinity, as the pH- will also drive your Alkalinity levels down significantly*

HOW MUCH TO ADD:

*These are estimated values to give you an idea of how much to put in your hot tub. Again remember, adding small increments & being consistent is more important than being exact*

Small Tub (68”-76”) 1000L  

Med Tub (78”-86”) 1500L  

Large Tub (88” – 96”) 2000L


24g or 2.5 Capfuls = pH under 7.2/1000L

36g or 3.5 Capfuls = pH under 7.2/1500L

48g or 4.5 Capfuls = pH under 7.2/2000L


CHLORINE     DAZZLE MINI CHLORINE TABLETS  

The WHY: Chlorine is an optimal choice for sanitization. Hot water is an ideal breeding ground for bacteria, and chlorine is quick & effective in killing bacteria regardless of the pH and alkalinity levels. It works by creating chemical reactions with oils, suntan lotion, moisturizers or anything else is left behind from bathers.

The HOW: For good measure, it's recommended to add two tablets of chlorine upon starting fresh, but not necessary until after your first use. After soaking in the hot tub, for maintenance, add the recommended amount of Chlorine tablets to kill any bacteria left behind. Having a chlorine reading on the test strip is (advised by Health Canada) but not necessary to safely enter the water for the next soak. Look for signs of clean water, including clarity and scent. If the water looks clear & smells clean, then often it is! 

HOW MUCH TO ADD:

0 – 0.5 ppm   WHITE  -  FADED  = Add 2 Tablets

1 – 3 ppm     FADED  -  LIGHT  = Add 1 Tablet

5 – 10  ppm      LIGHT  -  BRIGHT  = Add 0 Tablets


BROMINE         DAZZLE MINI BROMINE TABLETS

The Why: Based on personal preference of sanitization, Bromine can be used alternatively to chlorine. Bromine is a softer chemical and it's recommended to be dissolving in the water at all times. It also requires additional diligence to be effective. This chemical dissolves slowly and works best when your pH and Alkalinity levels are residing in their recommended ranges. 

The HOW: Add two tablets to a chemical floater or into your skimmer basket. For smaller tubs, add one tablet at a time. Add more tablets as they get close to dissolving. 


SHOCK      DAZZLE AMAZE & AMAZE

The WHY: Once Chlorine/Bromine comes in contact with organic material, it leaves behind chloramines/bromines, scented inactive particles that can no longer kill bacteria. These particles build up in the water and require oxidation to release them. Using a shocking agent designed for hot tubs will oxidize the chloramines/bromines, reducing the scent/irritations associated with these sanitizers. There are chlorinated and non-chlorinated shocks available. Having a chlorine-based shock will help when your water chemistry goes un-treated, and you need a quick-dissolving treatment as a boost to combat excess bacteria. 

The HOW: Once a week, put a cap full of Amaze Plus into the Hot Tub with the pumps on high speed and let the water circulate with the cover off for one cycle to allow for aeration. (Pumps should time out and turn off after about 15 minutes)

Additional Uses: 

  1. If there has been a hefty bather load, add a cap full of Amaze Plus after the tub has finished use for the day.
  2.  If the water becomes neglected & requires extra sanitization treatment, add a cap full of Amaze Plus in conjunction with chlorinating tablets. 

FILTER CLEANER       DAZZLE RAPID ACTION FILTER CLEANSE 

The WHY: The filter is responsible for catching particles and oils left behind by bathers. Cleaning your filter monthly will result in having cleaner water and reduced sanitizer usage. It is arguably the most essential component of Hot Tub maintenance. Dirty filters will result in poor water quality, as your sanitizer will use up its resources trying to combat bacteria/oils caught in the filter and not the bacteria residing in the body of water.

The HOW:

Every 1 – 2 Weeks: Rinse Filters with garden hose nozzle on Jet Spray to remove debris caught between the pleats. 

Every 2 – 4 Weeks:  After rinsing the filters, soak in a bucket with enough water to cover the fabric pleats and 1/3rd bottle of Rapid Action Filter Cleanse Solution. Allow to soak for about 1-2 hours & rinse with the hose. Alternatively, you can place Rapid Action Filter Cleanse in a spray bottle. Spray your filters down and let them sit for 1-2 hours, and rinse.
