Chlorinated and non-chlorinated pools freeze at the same temperature. However, salt water pools will freeze at a slightly lower temperature. It should also be noted that above-ground pools will generally freeze at a higher temperature than inground pools.
Do saltwater pools freeze? Yes, although their freezing point is just a bit lower than regular chlorinated water. Salt water pools freeze usually freeze closer to 28 degrees as opposed to 32, but nonetheless, they still freeze. So, treat it just like any other pool.
Winterizing a Saltwater Pool
Owners should always cover their saltwater pool when temperatures dip below freezing to retain as much warmth as possible — especially if their pool is heated. This can help prevent expensive damage and needed repairs.
It's much easier to winterize and put your pool enjoyment on hold during the off-season. If you've recently made the switch to a saltwater pool, you're also going to have to winterize and shut it down for the season.
Answer: It depends on a few factors. 1) are you closing your pool every year and therefore draining and refilling with fresh water at least a bit. 2) water chemistry - the more you have to add, the more your total dissolved solids will increase leading to the need to drain and refill.
You will want to use NaCl, sodium chloride, of at least 99% purity. To add salt, turn on your filter pump and add the salt directly to your pool water. Use a brush to help the salt dissolve and to prevent the salt from piling up on the bottom of your pool.
Salt stays in the water, so you only need annual boosters to replace salt lost to backwashing or splash-out. You can use the equation above to figure out exactly how much salt to add to keep the pool salinity at an ideal level.
How long should a salt cell last? The answer really depends on the use conditions and how often you do maintenance on your pool. The safe answer is that they usually last for about five to seven years. Salt Cells cost between $200 and $900 to replace, depending on your chlorinator model.
Corrosion is a common problem with saltwater pools. Saltwater systems pass salt through an electrolytic cell to produce chlorine. Pool water can become extremely over-chlorinated and corrosive if the sodium hypochlorite levels get too high.
Letting High Salt Levels Break Down Your Pool Equipment And Surfaces. Salt water isn't harmful in average concentrations. But if your salinity levels get too high or if it builds up on surfaces, it can start to break down your pool equipment, pool liner, and pool cover.
Can Saltwater Pools Be Heated? Saltwater pools are heated in the same way as standard chlorinated pools. These methods include a solar heater, solar blanket, heat pump, or an electric, gas, or propane heater. The least expensive and most eco-friendly is solar.
There's a danger of freeze damage to your pools if and when temperatures fall below 32 degrees Fahrenheit.
If you can't work on the chlorinator you work on the water. The other way to ensure that your salt water chlorinator works even in the cold is by investing in a pool heater. This allows proper monitoring and regulation of temperatures keeping them 60 degrees or above.
Shocking a saltwater pool is possible, although it might seem counterintuitive. Saltwater pools are theoretically self-cleaning, which means that shocks are not typically needed to sanitize the water. That said, most people still choose to shock their saltwater pools periodically to keep the water even cleaner.
So when it comes to day-to-day maintenance, saltwater systems are both easier and cheaper to maintain.
Shock your pool once a week with Salinity Surge Shock. Pool shock works as an added defense against bacteria and contaminants. With Oxidizing shock, you can use your pool after just 15 minutes! Shock your swimming pool on the same day each week for the highest benefits and keep your pool in tip-top shape!
There are several possible causes for a green pool:
Organic Matter – this might be a lot of dirt washing into the pool, or buds falling off of the trees, or algae that grew because the chlorinator failed to keep up. Cell Failure – your salt cell has a lifespan of approximately 10,000 hours.
Generally, you should always add salt to the deepest end of the pool. The additional water there offers the walls the most buffer from the dissolving salt, as well as often offers proximity to a main drain.
Every pool must turn over at least once a day, so most pool pumps should run approximately 8 hours a day. But here's the thing: you don't have to run your pool pump consecutively. You can choose to run it for three hours in the morning before you leave for work and another 5 hours in the evening.
Saltwater Pools Have Less Maintenance
While some of the basic cleaning duties are the same, such as skimming debris off the top of the water, applying a vacuum to the bottom, and cleaning the sides at the water line, the maintenance of the water is rather simple, simply add the required salt at the prescribed times.
When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
You'll spend about $100 per year on pool salt and chemicals for a salt water pool, $80 to $100 for monthly cleaning, plus $800 every three to seven years for a new salt cell. You may spend more on repairs too, as the salt can damage pool equipment.
