Happy Hot Tubs - the best for your hot tub

Happy Sparkle is used to add lustre and clarity to spa water.

Ideal for use with cartridge filter pumps as on most above ground pools and spas.

Cloudy water is caused by non filterable waste particles that are too small for the filter to remove. Spa Sparkle combines together fine particles of dust in your water making the particles bigger and easier for the filter to trap, resulting in clear water.
