Item Description

NLCT- Sea Blue - water clarifier

Quickly restore your spa water to perfect crystal clarity with NLCT Sea Blue

"Approved for all types of spas and hot tubs including wood"


Sea Blue


If you have tried multiple different spa water clarifiers but still are not able to get crystal clear water, then Sea Blue is your solution.

Northern Light's SEA BLUE is used to restore clarity in cloudy spa and hot tub water. SEA BLUE is compatible with all sanitizers including bromine, chlorine and biguanide.

Healthy clear water is one of the key elements involved in a relaxing hot tub experience. Very Fine particles can form in hot tub water. These particles are so small they don't get filtered out by the filter system. SEA BLUE causes these particles to attract to one another so they grow in size. The larger particles then get filtered out of the water through the filter system. It is these finely suspended particles that give the water a dull cloudy look. With SEA BLUE the water will quickly regain its sparkling clear brilliance!

Add 125 ml per 1000 liters of water.

  • Reliable, safe and effective

  • Adds Brilliance back to spa water

  • Aids filter system in removing suspended particles


  • Reduces and restores water clarity 

Size: 500 ml (17 FL Oz)
