My pool water is cloudy, smoky or hazy.

Possible Cause

Solution

Poor circulation or filtration. Back-wash and clean filter. Clean skimmer baskets and pump strainer basket. Filter may need chemical cleaning.
Improper water balance. Test pH, Total Alkalinity and Calcium Hardness. Adjust if necessary.
High Total Dissolved Solids (TDS) and/or Calcium Hardness. If one or both are high, TDS over 3,000 ppm or Calcium Hardness over 400 ppm, drain off 1/3 to 1/2 of your pool water and replace with fresh water. Then adjust chemical balance.
Excess organic waste. Shock with 1 gallon liquid chlorine for every 10,000 gallons of pool water.
High Total Alkalinity. Add Muriatic Acid or Suncoast pH Minus
Low sanitizer level. Add chlorine to bring it to its proper range.

My pool water is green.

Possible Cause

Solution

Green algae growth, a free-floating variety which imparts a cloudy green color to the water. It’s easy to correct if treated early. Shock pool and add Stop Yellow, Stop Green, Super Green Algaecide or All In One Algaecide.
Low Total Alkalinity Add Suncoast Total Alkalinity Increaser.

My pool has yellow or green dust on its floor and walls.

Possible Cause

Solution

Mustard algae. Shock pool and add Suncoast Stop Yellow.

My pool has black spots on its floor and walls.

Possible Cause

Solution

Black algae, a very resistant, hard-to-kill variety which appears as small, black dots or blotches that are pin-head to quarter-sized on the walls and bottom of the pool. Suncoast Super Black Algaecide is the finest product on the market for the treatment of black algae. If Metal Control is used in conjunction with Suncoast Super Black Algaecide, even the most severe problems can be eliminated faster. You need to brush the spots to remove them after chemical treatment.

My pool has pink slime.

Possible Cause

Solution

Pink Slime is a form of bacteria with a pinkish center that’s surrounded by a flat gelatinous mass. This bacteria can usually be tracked to some swimmer who has recently visited a coastal area where this type of growth is common. Double shock the pool with 2 gallons of liquid chlorine per 10,000 gallons of pool water. After 48 hours, use Suncoast All In One Algaecide at twice the recommended rate for visible algae.

My pool water is sudsy.

Possible Cause

Solution

Overuse of some types of algaecides. Discontinue use of current algaecide and switch to a high-quality, non-foaming one such as Suncoast All In One Algaecide. You may want to replace some of the pool water with fresh water and/or use Suncoast Stop Foam.

The pool water is making our eyes burn.

Possible Cause

Solution

Low or high pH Check pH and adjust to 7.4 - 7.6 range.
Excessive organic waste Shock with 1 gallon liquid chlorine for every 10,000 gallons of pool water.
Too much sanitizer Check automatic chlorinator setting.

The pool makes blonde hair turn green.

Possible Cause

Solution

Usually occurs in natural blondes or blonde children between the ages of 6 and 13, because of the amount of time they spend in the water. Also, certain forms of copper at concentrations of 1 or 2 ppm, like those found in some algaecides, can turn hair green. If the problem is due to reaction with a copper, consider a special shampoo. Shampoos, like those containing aloe vera or anti-chlorine shampoos, are available to neutralize the chlorine reaction. If copper is your problem, add a sequestering agent to disable the copper minerals in water.

The chlorine test turned orange.

Possible Cause

Solution

Pool water has a very high chlorine content, above 4 ppm. Discontinue using chlorine until chlorine returns to normal, or use a chlorine neutralizer.

The pH test looks purple or blue.

Possible Cause

Solution

Very high chlorine content. Neutralize chlorine and retest.

The pH test always tests too high.

Possible Cause

Solution

High Total Alkalinity Add Muriatic Acid regularly.

The pH always tests too low.

Possible Cause

Solution

Total Alkalinity is too low Add Suncoast Total Alkalinity Increaser.
Use of Tri-Chlor or other low pH disinfectants Use Suncoast pH Plus.
