8 best pool chlorine generators

Pool chlorine generators, also known as saltwater chlorinators or salt chlorine generators, are devices used to sanitize swimming pool water by producing chlorine from salt.Here's what you need to know about pool chlorine generators:

Saltwater Sanitization: Pool chlorine generators use a process called electrolysis to convert salt (sodium chloride) dissolved in the pool water into chlorine gas. This chlorine effectively sanitizes the pool by killing bacteria, algae, and other contaminants.
Reduced Chlorine Handling: One of the primary benefits of chlorine generators is that they reduce the need for traditional chlorine chemicals, such as liquid chlorine or chlorine tablets. This can make pool maintenance more convenient and reduce the potential for handling harsh chemicals.
Saltwater Sensation: While the water is chlorinated, it has a softer feel compared to traditionally chlorinated pools. Many people find saltwater pools more comfortable to swim in because they are less likely to cause skin and eye irritation.
Maintenance: Chlorine generators require regular maintenance. This includes checking the salt levels in the pool, cleaning the generator's cell, and ensuring the system is functioning correctly. The generator's cell can accumulate scale or debris, which needs to be cleaned periodically.
Initial Setup: To use a pool chlorine generator, you'll need to add the appropriate amount of pool-grade salt to your pool. The salt is dissolved in the water, and the generator converts it into chlorine as needed. The ideal salt concentration varies depending on the specific system you have, so it's essential to follow manufacturer recommendations.
Control and Monitoring: Many chlorine generators come with digital control panels that allow you to adjust the chlorine production rate and monitor the system's performance. This gives pool owners more control over water chemistry.
Cost Considerations: While chlorine generators can reduce the ongoing cost of purchasing chlorine chemicals, they do require an initial investment in the generator unit itself. However, over time, this cost can be offset by savings on chlorine products.
Compatibility: Chlorine generators are compatible with most types of swimming pools, including in-ground and above-ground pools. However, it's essential to select a generator that is appropriately sized for your pool's volume.
Health and Safety: Saltwater pools are generally considered safe for swimming, but it's important to ensure that the chlorine generator is operating correctly to maintain appropriate chlorine levels for sanitation.
Environmentally Friendly: Some people choose chlorine generators because they perceive them as more environmentally friendly than traditional chlorine chemicals. However, the environmental impact depends on factors like energy consumption and salt disposal.

In summary, pool chlorine generators are devices that use electrolysis to convert salt into chlorine, effectively sanitizing swimming pool water. They offer the advantage of reduced chlorine handling, softer water feel, and potential cost savings over time. However, they require regular maintenance and an initial investment in the generator unit. Proper setup, maintenance, and monitoring are essential for safe and effective use.

Circulation of Pool Water

A salt generator is typically last in line in the cycle of water running through your swimming pool. It starts with the pump drawing water from the pool and pushing it into the filter to be cleaned of any debris. If there is a heating system, the water would run through that next until it makes its way into the salt generators where it'll be sanitized and pushed out of the return and into the swimming pool. This operation replaces the tedious task of buying chemicals and pouring them into the pool, making for a simple and cost effective plan for the long term.

Ideal Chemical Levels

As with any pool, it is important that you maintain proper water chemistry of the pool water, including pH, alkaline content, and calcium levels. The only special requirement for HydroSalt is to maintain proper levels of salt and stabilizer. It is important to maintain these levels in order to prevent corrosion or scaling and to ensure maximum enjoyment of the pool. Test your water periodically.

Control Panel

This control panel helps make the job easier when it comes to monitoring your water. If needed add salt or run your pump for sanitation.

No Chemical Irritation

Say goodbye to irritating chemicals such as chlorine! HydroSalt automatically sanitizes your pool through a process called electrolysis. Bacteria and algae are killed by the salt converting into free chlorine.

Relax, It's Easy

The chemical reaction between the salt generator and the bacteria in your pool water makes it so you only need to add salt once.

Just Add Salt

The HydroSalt is an automatic chlorine generation system for pool & spa sanitation. The operation requires a low concentration of salt (sodium chloride) in the pool water at levels low enough that it normally cannot be tasted.

Question:	When installing, other than having the right voltage, what my cause have all the lights on but not start to generate
Answer:	Mine is red, and is not adjustable. I don’t know if it’s the same as the green one. Either way, it’s a flimsy product, I regret buying it.

Answer:	3 inch wide cutting surface
Question:	Have used this product for many years, find the housing for cell unit cracks. on 4th cell. cserv. has been good. any idea why housing cracks
Answer:	it depends on the material. It can cut a slice of onion thin enough that you can see through it. But it only can cut thin slices (not medium or thick slices)of relatively firm veggies, it doesn't do that well on meat and can't cut sea food or softer veggies, e.g.tomatoes, well.

Answer:	Dear Valued Customer, thank you for your question. Our product BLSW 10 use 1.4 A and 50 W, which could help you.
Question:	How do tell what % to set the cell at
Answer:	Depending on the size of your pool I would start at the max setting. Test the chlorine level each day for a week or so and adjust accordingly. I use one an 18x33 oval pool and I have to keep it running on max to keep my chlorine at the correct level. I think my pool is the maximum size for this unit anyway. Hope that helps.
