Fiberglass pools will now look virtually the same for many years. This improvement in longevity of the finish visually also means the finish will stand the test of time when impacted by pool chemicals.  This includes a salt water fiberglass pool.

If your fiberglass pool has an automatic cover or a handrail, you will still need to be concerned. You will need to actively focus on maintaining each of these when you have a salt system. Handrails made of 304 stainless steel will rust when exposed to salt water.  You need to replace your handrail with one made of marine stainless steel grade 316 if you want to avoid corrosion.  Likewise you’ll need to keep your automatic cover rinsed and cleaned regularly to avoid premature corrosion.

Patio And Stone Work

Also, you’ll still want to keep an eye on your patio. Salt water can damage stone work and concrete when exposed over a long period of time. You may want to consider having your stone work sealed with Stain Proof sealer.
