7 ways you could be slowly eroding and corroding pool surfaces and equipment. 7 corrosive culprits that are eating away at your soft and shiny pool surfaces.
1. High Chlorine
Excessively high levels of chlorine certainly kills harmful bacteria and other nasties in your pool water but it is especially harmful to your solar covers, pool liners, pool covers, Pretty much anything that is soft and flexible can fade or become brittle with high chlorine levels. So, when you have to shock the pool, take out the pool cleaner and pool floats, and leave the solar cover off for a few days.
Mulch looks beautiful, but if it blows in or washes into the pool, it brings high levels of phosphates and nitrates, and other chemicals you don’t want in your pool. Secondly, mulch is very acidic and holds in moisture. Wood mulch around your pool pump or heater blocks air flow, and the acidic humidity is bad for steel equipment, electrical motors and circuit boards. Gravel or rubber mulch are better alternatives.
Saltwater pools have many benefits, but salt can degrade soft stones used around swimming pools. Stonework used for coping, raised walls or pool decks should be sealed, and rinsed regularly to stop corrosion. Salt can also damage metal surfaces inside the pool with galvanic corrosion, and can lead to surface damage to steel items in the pool. Using a sacrificial Zinc Anode will prevent the issue.
4. Too Much Sun
Another destructive force on your pool is the very reason most of us own a pool in the first place: the sun! We all know that the sun’s UV rays are harmful to anything if exposed long enough and your pool, solar covers and pool equipment is no exception. Many pool items are made of plastics and there are few things the sun loves to fade and degrade more than vinyl and plastics.
5. Too Little Sun
The opposite of too much sun can be true as well! The sun has natural sanitizing properties, and is good for your pool water health, in fact did you know that the top few inches of pool water is more sanitary than deeper water? That’s due to the natural UV sanitation. Too little sun can also affect your perfect summer tan so many of us aspire to, but more importantly, it invites mold and mildew to dark and wet areas.
6. Leaves and Debris
Tannins and acids in tree and lawn debris can stain and damage pool surfaces and can throw pH or Alkalinity out of whack. They also bring phosphates and other undesirable micro-contaminants into the pool, which consumes sanitizer, and becomes food for algae. If your trees could use a trim, your water quality should go up, your workload should go down, and your tan should improve!
7. Low Pool Chemistry
Last but certainly not least important, the granddaddy of all corrosive agents around swimming pools is acidic water chemistry. Low pH, low Alkalinity, and low Calcium Hardness, can all stain and damage plaster, tile, vinyl or fiberglass, steel, rubber, and can even destroy pool filters and heaters. It’s the first rule of pool club: Balance your water. You know the second rule of Pool Club? Balance your water.
