When the free chlorine level is low, that usually means it's time to add more salt, but it may mean a couple of other things as well. For instance, low chlorine readings can indicate that you need to increase the chlorinator output or run it more frequently.
If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
Pros of Saltwater Pools
There's less chlorine and less of the heavy chemical scent and content. They're gentler on the skin, with less irritation to the eyes, hair and swimsuits.
Saltwater pools are also generally the cleaner of the two. Having a salt water pool could also be safer than having a chlorine pool. That's because, with a salt water pool, you don't have to store all the harmful chemicals that are needed with a chlorine pool.
Maintain Proper pH Levels
Your pH levels affect your chlorine levels and the ability for the chlorine to do its work properly. If your water's pH is too high, it hinders the chlorine's ability to efficiently clean the pool. A water pH level that is too low causes the chlorine to dissipate more quickly.
When you're shocking a pool, the goal is to raise the free chlorine level of the pool water to roughly 10 times the combined chlorine level. Reaching this mark is the breakpoint chlorination. Shocking a pool should be done at dusk. The sun will burn off unstabilized chlorine.
How do you raise the free chlorine in a salt-water pool? You can use granular shock or shock pods in your saltwater pool. Just make sure that you use your long-handled pool brush to disperse any shock that settles to the bottom.
Annual booster additions of pool salt are usually required, but only to replace salt lost from backwashing, splashout or lowering the water for winter. If you fully drain the pool for maintenance, you will need to replace all of the pool salt.
So, not only is shocking a saltwater pool okay, but it's actually important to your pool's health. Shocking is the process in which you overload your pool with chlorine (3-5 times the normal amount) to improve your pool's cleanliness and kill off organic matter.
The easiest way to be certain if the chlorinator is working is to make sure the cell is clean by checking the needle or production lights on the chlorinator box. When operating, you should also see bubbles (hypochlorite gas) inside the chamber, producing what looks like cloudy water - that's chlorine being created!
If you're using the Water TechniX Salt water chlorinator then you should try to aim for a salt level of around 3,000 to 4,000 ppm.
One of the causes of a high chlorine demand is an excessive buildup of algae and phosphates. Although you're adding chlorine to your water, bacteria or algae are overpowering the chemicals causing it not to show up on tests strips or in water kits.
We're probably all familiar with at least one of the common side-effects of swimming: sore eyes, skin irritations, fading swimming costumes, and that lovely smell that lingers until you've had a good shower. But chlorine itself, when used at the recommended low levels, is perfectly safe.
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.
Low levels of chlorine or bromine may not be able to kill algae spores, resulting in algae blooms and cloudy pool water.
Is a salt water pool easier to maintain? Yes, a salt water pool is easier to maintain! There's no need to purchase, store and add chlorine to your pool. Simply add salt and your pool's salt chlorinator will do all the work of making chlorine.
Saltwater pools can definitely be heated just like freshwater pools. The saltwater chlorinator does not affect heating units, so you will not have to worry about this when installing a heater in your swimming pool. The heating units will also be set up and installed in the same way as in chlorine pools.
Salt water offers a pleasant healthful swimming experience with fewer chloramines produced, eliminating the harsh chemical odor. Salt cells convert salt into active chlorine for a lower cost as compared to the traditional form of liquid or solid chlorine.
If you own a salt water pool, you probably know how big of a problem algae growth can be. Once these organisms contaminate the pool, they can grow and spread quickly. Both chlorinated and salt water pools need proper water chemistry levels in order to prevent algae growth.
