Which is Best: Fiberglass, Concrete, or Vinyl Liner?Mike Miller
Fiberglass Pool Advantages
Why are fiberglass pools so easy to maintain? It all has to do with surface porosity.
The surface of a fiberglass pool, called the gelcoat, is virtually non-porous. In contrast, the surface of a concrete pool is extremely rough and porous.
These rough cavities and pores give algae a place to hide and call home, making pool ownership much more difficult.
Concrete pool builders teach their clients that weekly brushing of the entire pool surface is mandatory to keep algae at bay.
In addition, chemical usage in concrete pools is much higher because of the need to penetrate the pool surface to kill algae.
Concrete pools also require daily doses of muriatic acid to lower the pH of the water. This is because concrete is alkaline based and constantly increases the pH of pool water. Fiberglass pools, on the other hand, are inert and do not effect water chemistry in any way.
For these reasons, fiberglass swimming pool owners typically spend 75% less time and money maintaining their pools. This means anyone who owns a fiberglass pool will spend more time in the pool and less time maintaining it.
