How to Start Up a Hot Tub Salt System

Genesis Start-Up with Blu Fusion TS

Before starting up your hot tub salt system be certain to start with a clean spa. It is also important to use cleaning products that do not contain phosphates as phosphates will deplete free bromine and are a super-food for algae. Always start your spa with a clean filter. You can test the water with the supplied test kit or purchase another phosphate test, as needed. Ideal phosphate levels with the Blu Fusion TS Salt System is 0-30 Parts Per Billion(PPB), if your phosphate levels are high you can reduce the levels with Phosklear 4000 or a 3 in 1 product: Free & Klear – Enzyme, Clarifier & Phosphate Remover.

If the water source is well water you should have the water tested for Total Dissolved Solids(TDS) and metals. Water with high TDS is likely to have higher metal content and will need a metal remover like Leisure Time – Metal Gone and/or Unique. Starting TDS level should be 50-200 PPM.

Your local hot tub dealer should be able to test for Metals, TDS and Phosphates, Give them a call to verify their procedure for water tests.

  1. Using the supplied Pre-Filter, fill your spa with water to the recommended level, do not fill with water from a residential water softener.
  2. Before starting the system, balance your water chemistry to ensure a successful start up, Ideal Ranges:
    • Total Alkalinity – 80 to 120
    • pH – 7.2 to 7.6
    • Calcium Hardness – 150 to 250 PPM
    • Phosphates – 0 to 30 PPB
  3. Determine the level of “NaBr” (Sodium Bromide) required for your spa size. NaBr should be added at a rate of 1.2lbs per 100 gallons or 1,300-1,500 PPM.
    • Example: For a 500 gallon spa add approximately 6lbs of NaBr.
  4. Turn jets on high speed, broadcast/sprinkle the NaBr across the surface of the water to help evenly distribute the NaBr into the spa and let circulate for 30 minutes.
  5. Test the Sodium Bromide concentration with the Tru-Blu NaBr test kit. If you have added the correct amount of NaBr, you should have a reading between 1300-1500 PPM.
  6. Adjust the filtration time to circulate a minimum of 8 hours every 24 hours on a 2-speed pump.
  7. For an average spa between 300-500 gallons we recommend starting at a power setting of “6” and then press the “boost” feature. This will accelerate the production of the bromine level for the next eight (8) hours. Do not immediately enter your spa, wait until proper bromine levels are reached.
  8. Always keep your bromine level between 3-5 PPM. The spa size, filtration, and bather demand will determine what maintenance setting is required. Test your bromine level after 24 hours and adjust the power setting up or down depending on the bromine levels that are indicated. Adjusting more than 1 setting at a time will have a significant impact on the daily bromine output. For the occasional heavier bather load, you may press “boost” instead of adjusting your power setting.

WATER CHEMISTRY
Spa owners should purchase Bromine/ pH/ Total Alkalinity/ Hardeness test strips and test spa’s water regularly to ensure that pH, Alkalinity and Bromine levels are in the proper range. Never enter a spa that has cloudy water or insufficient bromine levels. We have a variety of chemicals to increase or decrease your pH value and Total Alkalinity. If you are unsure how to use these chemicals after reading the products directions, consult your dealer for assistance.


HOW MANY HOURS A DAY SHOULD MY LOW SPEED PUMP CIRCULATE?
Circulation time is a very important element for clean and inviting water. Eight (8) hours is the minimum circulation time needed for Genesis BLU FUSION to create the proper amount of bromine for your spa. Your system should only be powered on and producing Bromine when your spa is circulating. It is recommended to use a 24- hour circulation pump for spas over 1,000 US Gallons.


FINDING THE RIGHT POWER SETTING is really quite simple.
For a spa filtering 8 hours per day adjust the setting on the Genesis controller to a setting between 6-8 (eg. 400 gallon spa). For 24 hour circ pump a lower power setting is typically needed 2-4 (eg. 400 gallon spa) Test and monitor the Bromine level with a Bromine test kit. The recommended level for bromine is 3-5 PPM.
Should your bromine elevate above 5 PPM, reduce power setting daily until the desired bromine level is achieved. Adjusting more than 1 setting at a time will have a significant impact on the daily bromine output.
