What chlorine generator works best?

Answer 1

A salt generator produces chlorine. Salt is NaCl (sodium chloride) and when it goes through the salt cell it seperates the sodium chloride thus making chlorine. So, all of the above mentioned choices chlorine tabs, salt generator, and chlorine ozone system all use chlorine as the primary sanitizer, just in different dosages. With the salt system, it is run on a lower chlorine level thus reducing some of the effects of chlorine. It can be a great way to sanatize the water, however, if you have or are installing any soft stone around the pool, beware of the salt system, it discentigrates the stone with water splash out. Also, the salt cell's do no last as long as they are suppossed to. I have seen them replaced in as little as 1 year. This can be very costly. I see it alot, being in the business, most people who put salt systems on their pool end up just using regular 3" tabs when the salt cell burns out. Lastly, when you put an ozone system on your pool, you still have to use chlorine as the primary sanitizer, just in lower doses as stated in the last answer below.

From what I understand from my pool wholesale shop, The salt generator is the . The ozone purifiers don't work as good, and chlorine, While the mainstay for most pools, works very well keeping the water clean and clear, but has the Chlorine issues. ( Harsh chemical, corrosive, dangerous to handle, bleached swimsuits, green hair, burning eyes) I am installing a Salt Generator in my pool in the next couple of days, I like the automatic features, and the low cost of continuing service, and the self cleaning of the I am getting. Hope this helps.

None of the above are "best"! Salt systems like chlorine generate harmful disinfection by products (DBP). Look into Ultraviolet technology.

I agree with Jon, the Ozone is not a stand alone system, it just provides the oxidation of the water. You still need to maintain a Chlorine residual of 0.5 to 1ppm. You can use the two systems together for the best effect and the Ozone system will actually double the life of the salt cell.

I own and operate a small pool construction/service business, in my experience corona discharge ozone units sized properly are a wonderful addition to chlorine treatment. they do NOT replace chlorine but do reduce the amount needed to maintain 1.5 ppm and help maintain a much nicer cleaner looking and smelling pool. ozone is an extremely strong oxidizer and burns away many impurities instantly but provides no residual affect or treatment for "dead-spots" uv ozone generators in my opinion produce to little ozone to be effective and most that I have tried burn out in no time.

PS i have no experince with salt generators I have read alot about them but have not seen any in my area yet

I will start by saying that I DO work for an Ozone Generator Manufacturer. I partially agree with the above answer as far as Ozone not being a "stand alone" system. Ozone has a very short half life so when the pool pump shuts off the Ozone production is stopped as well. You still need to maintain 0.5 to 1ppm of Chlorine or Bromine residual to act as a "buffer" and sanitizer.

The part of the above answer that I DON'T agree with is the Corona Discharge (CD) statement. There are 2 different ways to produce Ozone on site at a residential pool/spa application as follows:

1. Corona Discharge (CD) - Ozone is created by creating an electrical arc over a tiny gap on a metal "chip" inside the unit. This initially creates a large amount of Ozone, but the "chip" is very short lived. The problem with this method is that unless an air dryer or prepared oxygen (tank) are used, Nitric acid will quickly build up on the chip, eliminating Ozone production within months.

2. UltraViolet (UV) - With this method, Ozone is created by passing ambient (outside) air across 1 or more specific wavelength UltraViolet lamps. The amount of Ozone produced with this method is less than that of the CD method, but still more than enough for the intended applications (pool and spa water). The UltraViolet method will produce sufficient Ozone for roughly 10,000 hours before a lamp change is needed.

The other important factor when looking at an Ozone system is the installation method. These systems can either be installed on the suction or pressure side of the pool pump (depending on manufacturer) which will make a large difference in the effectiveness and benefits of the unit. If the unit is installed on the suction side of the pump the Ozone is injected into the highest pressure point of the system which is between the pump and filter. This forces the Ozone mixture into the water and uses the filter as a reaction chamber, giving the Ozone adequate time to oxidize the non-living bather wastes in the water. As a "side benefit" this installation also extends the time between filter cleaning as the Ozone degreases the filter as well. If the Ozone is installed on the pressure side of the pump, it doesn't have enough time or pressure to effectively oxidize the water, it mostly just runs along the top of the return line and off-gases when it gets to the pool returns.

Answer 3

Magnapool distributed in Australia by poolrite This system works with Manesiumand potasium chloride rather then potasium chloride which is the norm at present. It is healthier and the back wash can be used to water the garden if you like. as amater of fact its good for it and the salts used are also good for people

Answer 4

The best that I have seen is the new Magnablu system sold in Australia by Poolrite
