Can I Choose an Alternative to Chlorine with a Fiberglass Pool?

Dec 03, 2020

That familiar chlorine smell is something that’s widely associated with swimming pools. While many pool owners like the sanitizing power of chlorine, others love the idea of using an alternative purifier to keep their water clean and healthy.

Not every type of pool is compatible with every type of sanitizer though. If you’re planning a fiberglass pool and are interested in an alternative to chlorine, you may be curious about your options.

Options

When it comes to choosing a pool sanitizing system other than chlorine, your main choices are salt water or mineral water. Luckily, they are both fantastic options for fiberglass pool owners. In fact, pretty much any system works well in fiberglass, so your choices are quite open. 

Salt vs. Mineral

So what are the benefits of each of these systems? Skin, eyes, and hair are far less irritated in salt water versus traditional chlorinated water. It also doesn’t break down swimsuits like chlorine does. The feel of the water is softer, which many swimmers find very appealing.

Also, those caring for the pool don’t have to handle harsh chemicals when doing cleaning and maintenance. Storing the salt products is safe, and they tend to be less expensive than the alternatives.

Mineral systems use a small amount of chlorine in addition to minerals like magnesium chloride to keep the pool water clean. Like salt water systems, mineral system water feels softer than traditional chlorinated water.

These systems are also gentler on skin, eyes, and hair, due to their lower chlorine content and the inclusion of magnesium and other minerals that provide an exceptional swim experience.

Metal Corrosion

Unlike vinyl liner pools, which tend to have metal components in the water, fiberglass pools have a smooth interior. With their strong, non-porous surface, salt water is not a corrosion issue in a fiberglass pool.

Over time, salt water corrodes metal surfaces such as fittings and ladders. However, fiberglass pools are constructed to be one solid piece. Stairs and ledges are built-in, so there is no need for metal ladders to be added.

Surface Corrosion

Salt water can be incredibly hard on concrete and gunite pool surfaces. The salt is abrasive to these materials, causing them to break down much more quickly. It can also stain the surface, causing it to look less inviting.

In addition, the salt water is hard on the plaster paint that’s often used in concrete pools, meaning they have to be refinished more frequently. Fiberglass pools, however, hold up very well with a salt water system.
