Sodium Bromide Test Strips
  • Effective and always helpful in managing water chemistry
  • Gives you an understanding of how to interact with you spa water

About Test Strips

TRU BLU Test Strips are available through all authorized BluWater Technology dealers. The use of these strips will help you determine how much, if any, additional TRU BLU Salt to add to your water due to evaporation and/or removal.


(Does not test for Bromine) 1. Fill a small glass with one inch of pool/spa water. 2. Insert lower end of strip into water. IMPORTANT: Keep top half of strip completely dry to get an accurate reading. 3. Yellow band will turn dark when test is complete (should take 3-4 minutes). 4. A reading of between 1,900 and 2,100 ppm is recommended.

Water Chemistry

REMEMBER: ALWAYS ADD CHEMICALS TO WATER NEVER WATER TO CHEMICALS Water chemistry must be balanced before starting up The GENESIS Device. If the water is not properly balanced, The GENESIS Device will not create Bromine.
  • pH Ideal range 7.2 – 7.8, test weekly
  • Alkalinity Ideal range 80 - 120 ppm, test monthly
  • Calcium Hardness Ideal range 80 – 150 ppm, test yearly
TDS – Total Dissolved Solids:
  • Ideal range before adding Tru-Blu: 200 – 500 ppm
  • Ideal range after Tru-Blu has been added: 1700 – 2300 ppm
  • Phosphates – level should be less than 100ppb
Adjusting Water Chemistry: Follow the label instructions based on your tub size. We recommend Biolab, Leisure Time, and Blue Wave products. See your local pool and spa dealer. Adjusting your pH:
  • If pH is low (below 7.2), raise by using a base baking soda or soda ash product.
  • If pH is high (above 7.6), lower by using a muriatic acid or sodium bisulfate product.
Adjusting your Alkalinity:
  • If Alkalinity is low (below 80), add baking soda product.
  • If Alkalinity is high (above 120), add sodium bisulfate product.
Adjusting your Calcium Hardness:
  • If Calcium is low (below 80), add a calcium chloride product.
  • If Calcium is high (above 150), partially drain the tub and refill with fresh water.
Adjusting your TDS – Total Dissolved Solids: Total Dissolved Solids are a combination of metals, minerals and other organic materials in your water. If your spa has been filled with well water or with water from a non-municipal source, additional chemicals to remove metals and or chemical contaminants may need to be added to your water. TDS can be tested with a meter, test strip, or by taking a water sample to your local pool and spa dealer. Phosphate Contamination: Phosphates are contaminants that come from products such as fertilizer, soap, shampoo, lotion, and perfume. Phosphates can be tested with a strip or by taking a water sample to your local pool and spa dealer. *Some spa chemicals such as spa filter cleaners and salt water softeners contain Phosphates and should not be used.
