Can Fibreglass Pools Be Saltwater?

Fibreglass pools have become increasingly popular over recent years. One of the most frequently asked questions by pool buyers is whether saltwater can be used in pools; the answer is yes. 

The most common misconception regarding saltwater pools is that they are as salty as the sea. But this is untrue. It is so much less salty than the sea that, at most times, it is unnoticeable. While a chlorine pool uses huge amounts of chlorine in the form of tablets, powders, or liquid, a saltwater pool uses a salt-chlorine generator that converts salt into chlorine. The salt added should be enough to run the chlorinator. This will help to keep the pool healthy and clean without adding harmful chemicals to it.

Concrete pools and saltwater

It is not advisable to install a chlorinator in a concrete pool since it can cause gradual corrosion of its cement finish since dissolved salt can act as an abrasive. If a chlorinator is installed in a concrete pool, it will need to be resurfaced more frequently, making it a costly affair.

Vinyl pools and saltwater

Saltwater can cause galvanic erosion of vinyl pools that have steel walls. The salt will damage all the metal structures that are present in the pool.

Fibreglass pools and saltwater

Fibreglass pools are extremely compatible with salt-chlorine generators, and the pool shell acquires no detrimental effects due to the salt. The bacterial and algal growth in fibreglass pools is extremely low owing to their smooth and non-porous surfaces.

It is important to wash the area around the pool after every use to prevent the buildup of salt that can corrode metal fittings, if any.

A major consideration that features in buying a pool is its cost. When the cost of saltwater pools is compared to that of chlorine pools, it can be seen that saltwater pools are costlier than their counterparts. But this is offset by the fact that the salt used is quite cheap when compared to chlorine. It allows people to go to saltwater pools without causing much of a dent in their budgets.

Saltwater pools, like any other pool, have both benefits and drawbacks. All these points should be taken into consideration before deciding to buy a pool.
