Everybody has different swimming preferences. Fortunately, there are plenty of options available for your backyard pool.
Ultraviolet Light Systems (UV)
Ultraviolet (UV) pool sanitizers use a non-chemical system of invisible UV light rays to sanitize water. Ultraviolet pool sanitizers emit a high intensity light ray that destroys algae, bacteria and viruses, as well as some chlorine-resistant parasites. UV systems also eliminate the formation of chlorine by-products.
About 80% of new water parks and aquatic facilities use ultraviolet sanitation systems.
Although UV light systems effectively kill many germs, the system must be used along with chlorine for residential pool sanitation. That’s because UV systems work by moving the pool water past the UV lamps, where germs are destroyed. In residential pools, unlike many waterparks, water doesn’t circulate quickly enough around to the UV light. That means it may take too long for germs in the distant part of the pool to get exposed to the ultraviolet system.
During that lag time, bacteria, algae, viruses and parasites can grow and multiply. So adding germ-killing chlorine to a UV system is ideal for a residential pool. But you should still consider installing a UV sanitizer since it should help you decrease the amount of chlorine needed for your pool.
he UV system itself is super low maintenance, typically needing only a yearly UV lamp replacement and a cleaning of the quartz tube that’s inside the UV unit. But remember you’ll also need to add chlorine regularly for optimal sanitation.
Lots of people think that a saltwater pool is better than a chlorine pool. But, in a way of speaking, a salt water pool IS a chlorine pool. The chemical name for salt is sodium chloride. Remember that from chemistry class? In a saltwater pool, sodium chloride is electrically converted into chlorine.
Because they have lower chlorine levels, salt water pools are much gentler on the eyes and skin. Research indicates that salt water systems may be safer than chlorine pools, which force owners to store and handle unsafe chemicals. … Salt water pools produce softer-feeling water, which many find desirable.
Although a significant amount of salt is dissolved in the pool water to clean and sanitize the saltwater pool, the water won’t taste really salty like ocean water does. In fact, saltwater pools have 1/10 the salt of the ocean.
The initial up-front cost of the saltwater pool is much greater than the up-front cost for chlorine, as we just discussed. But over time, the cost goes down significantly because it’s mainly the water in the pool that’s lost or gained, not salt. The amount of salt in the pool remains relatively stable, so only small amounts have to be added to maintain salt-to-water ratio.
- They can cause dry skin, red eyes, bleached swimwear and irritated noses, throats or lungs.
- You must keep chlorine products on hand, which cost more than pool grade salt.
- Chloramines may cause a strong “chlorine” smell, especially if you have an indoor pool.
