FIBERGLASS INTERIORS

Fiberglass interiors can be found in one-piece

fiberglass pools, pool walls constructed of fiberglass

panels or as a lining to the interior surface of a

concrete pool structure.

Fiberglass interiors provide a

smooth, non-porous surface that requires minimal

maintenance or brushing and have no affect on the

pool water chemistry.

Your fiberglass pool interior may or may not have a ceramic or adhesive tile border.

You

should regularly clean the fiberglass or tile at the waterline using a tile or surface cleaner

available from your pool professional with a sponge or soft brush.

DO NOT

use abrasive

cleaners, steel wool or metal brushes to clean the pool or you may permanently damage the

fiberglass or tile surface and cause rust stains from the steel or metal.

Cleaning the pool interior below the waterline simply consists of routine brushing and

vacuuming. Please refer to the

Vacuuming

or

Routine Maintenance

section for more

instruction.

Do not allow organic materials (leaves or dirt) to lie on the pool surface. Promptly

remove with a net or vacuum to avoid possible staining or discoloration.

Water chemistry is important! As mentioned above, fiberglass interiors do not affect your pool

water chemistry BUT they can be affected by water chemistry. Just like any other pool interior

surface- it is important to maintain balanced water at all times, paying particular attention to

pH, Total Alkalinity and Calcium levels.

The following are general water balance guidelines for

a fiberglass interior, be sure to refer to the manufacturers information that came with your pool

to be sure these suggestions are the same.

Water balance and chemical parameters are

mentioned in greater detail in the

Basic Water Chemistry

section.

pH

7.4-7.6

Total Alkalinity

80-150 ppm

Calcium Hardness

225-325 ppm

Total Dissolved Solids

1500 ppm or higher / max 2500

*NOTE:

Some Fiberglass manufacturers’ recommendations for Total alkalinity and Calcium

Hardness levels may vary quite a bit from one end to the other.

The parameters listed above show

the lows and highs of most fiberglass pool

manufacturers.

It is important to have your pool water tested for mineral and metal content by your pool

professional.

All water will have some level of metals present that are not visible becasue

they are completely dissolved. Your pool professional can recommend a sequestering chemical

or metal chelating product to aid in the removal of metals introduced to the pool by fill waters, rain

and the corrosion of metal equipment. If un-treated, fiberglass will act like a magnet to draw

metals out of suspension and the result can be staining, shading, or blotches to your pool

surface.

See

Staining and Scaling

for more information.

NOTE:

NEVER DRAIN a one-piece fiberglass pool without contacting the manufacturer. If conditions

exist that require your pool be drained you must FIRSTconsult your pool installer or manufacturer.

Improper draining can cause hydrostatic ground pressure to lift, crack, or damage the pool structure.
