Pool Surface Problems

PROBLEM:  Oil or scum line (bath tub ring)

POSSIBLE CAUSES:  Overuse of cosmetic products, accumulation of body oils or airborne contaminates.

SOLUTION:  Use SUN Tile & Vinyl Cleaner on the affected areas. Try to reduce the amount of cosmetic residue being introduced into the water. Shock the pool on a regular basis to control and remove the accumulations of oily deposits.


PROBLEM:  Scaling/Deposits/Rough surface

POSSIBLE CAUSES:  Unbalanced water: High pH (above 7.6), high Total Alkalinity (above 150), or high Calcium Hardness (over 400 ppm) — possibly from long-term use of products containing calcium,

SOLUTION:  High levels of calcium hardness can result in the formation of scale deposits on the underwater surfaces. High pH and TA will worsen the problem so it’s important that these parameters are optimized. SUN Scale & Metal Control II can be used to help deal with the scale formation. Avoid using chlorinating products containing calcium for daily use or shocking. SUN-Burn® 35 or SUN Shock ‘N Clear® Multi-Purpose Shock as well as SUN-Brite® Non-Chlorine Oxidizer offer performance and convenience without any calcium.


PROBLEM:    Corrosion of Metal Parts/Pitting

POSSIBLE CAUSES:  Unbalanced water: Low pH (below 7.2 ppm), low Total Alkalinity (below 125 ppm), low Calcium Hardness (below 150 ppm), failure to test pH frequently and adjust accordingly or placement of chemicals on metal surfaces.

SOLUTION:  Water testing is important to avoid the conditions that lead to corrosion. Maintaining proper levels for pH, Total Alkalinity, and Calcium Hardness will help minimize corrosion. Never place chemicals on metal surfaces.


Hints/Preventive Maintenance: Pool surfaces can be affected by the water conditions that are maintained during the season, as well as the quality of the water used to fill the pool. Improper control of pH, Total Alkalinity and Calcium Hardness can cause scale formation, pitting, corrosion and staining of the underwater surfaces. Regular water testing should be practiced. Always follow label directions carefully.
