All the pretty colors. Great when in a rainbow. Bad when in your spa. Spa water should be crystal clear. So when your spa water is yellow, what does that mean?
Here’s a quick synopsis of what these colors mean:
Dude, you got algae in the water.
Treatment: Shock your water with chlorine.
See-Through Green or Emerald Green
Acidic Water. The metals in your heating elements are being stripped. The average cost for a replacement heating element–$200-$250 big green dollars (includes labor).
Treatment: Try a product like Metal Gon by Leisure Time–then balance your chemistry.
Total Alalinity 80-120, pH 7.2-7.6, . If this fails, drain and start all over.
Indicates low total alkalinity and low pH. It’s also the precursor to damaging the spa’s heating element.
Treatment: Balance your total alkalinity and pH. Also check your calcium hardness — should be over 250 ppm.
Treat with calcium increaser.
Blue rarely happens in above ground spas. But in-ground gunite spas– with gas-fired heaters–can experience bluish/turquoise water, as well as the same color stains on the plaster.
Treatment: Get the total alkalinity pH, and calcium hardness balanced. Also check total dissolved solids (TDS) –not over 1500 ppm– because that can also begin striping your heater.
Rare, but happens. Usually indicates iron in the water.
Treatment: Metal Gon should cure it. If it continues, drain, refill and add a bottle of Metal Gon when you refill.

The pool and spa master challenges his readers to sign up for an International Coastal Clean Up day, September, 19, 2009. You don’t have an ocean? There are river clean ups too! They all flow to the sea.
