Intex krystal clear saltwater system and ozone filter. only ozone provides virtually complete, instantaneous, odorless, all-natural sanitation of pool water. ozone eliminates bacteria over 3, 000 times faster than chlorine and because it has up to 100 times the oxidizing power of chlorine, it cleans pool water without the chemical smell that swimmers often associate with chlorine.

Functions ok, water flow bad. The reason for only three stars.
I bought this item at Walmart for $129, free shipping. One end of the hose had a broken screw-on bracket. The GFCI cord quit working after about a minute. I called Intex and was quickly connected to a helpful Virginia. She arranged to send me the replacement parts, shipping within two days.
In the meantime, I attached the broken end of the hose with a clamp to an adapter and took the GFCI apart. Someone had forgotten to tighten down the electrical leads!!! After tightening, it worked perfectly. So I will have a spare when the replacement arrives. I see that the other reviewer had a problem with the cord. Intex is losing a lot of money for forgetting to tighten three screws.
The unit can cycle on even on the low speed of my Pentair 1HP two speed pump. There is plenty of flow though my oversized Hayward S244T sand filter. After six hours at low speed, my 10k gallon in-ground pool went from 0.5ppm to 2.5ppm free chlorine. Great! When it finishes one full change of water, I expect it will be at 5ppm, which is what I measured testing directly from a return outlet.
My Floatron is now probably overkill with the ozone. The ozone kills the bad stuff in the unit, while the Floatron emits copper and silver ions to do the job in the pool. Either one lowers the chlorine demand (the amount of chlorine you need to maintain a certain ppm).
You should always target a free chlorine residual that is about 10% of your cyanuric acid (CYA) stabilizer reading for the quick reaction that you need for real bather load. I am intending to dilute CYA down to 30ppm, target my runtime for 2ppm, and float a stabilized chlorine tablet for 1ppm (thus 3ppm total of free chlorine). The chlorine tab is acidic and will offset the alkalinity of the salt water system. Backwashing the sandfilter every month will keep the CYA in the 30ppm range despite the dissolving tablet. So there you have it, a safe, clean, minimum maintenance, cheapskate's pool!
The unit overall has a two year warranty, with one year on the titanium electrode and the ozone cell. Even if you have to replace it every one or two years, it is a much better deal than any other salt system out there, whose replacement salt cell can cost you a many hundreds every couple of years. Intex says this unit is for above-ground pools, but I had no problem adapting it to my in-ground pool.
The broken hose bracket makes me nervous. I might replace some of the cheap intex external components with heavier stuff.
Reluctantly I will return this unit because it is incompatible with my pressure-side pool cleaner, a Polaris 360. The ozonator works by venturi action, sucking ozone and air from a discharge chamber. Even when the unit is off, it sucks air. This results in ozone and/or air bubbling into the return line. This causes my Polaris to fill with gases and float to the surface where it is almost useless as an automatic pool cleaner. If you don't have a pressure-side cleaner, you should be fine. I will buy the unit with a copper ionizer instead of the ozonator. If you want the ozonator, Walmart dot com has the current unit on clearance for $119.
I figured out a way to keep it. I disabled the ozone and air sucking by putting a rubber stopper into the venturi hole after removing the ozone unit. So now it just generates Chlorine which is fine with me, especially for the new clearance price of $79.00. I applied to Walmart to refund the difference (I paid $149) and ordered two more at $79. I still have the Floatron for Cu and Silver ions if I decide I need that. Assuming these intex units last for two years each, I've spent about $240 for 6 years worth of Chlorine. Not bad. All three combined are still much less than the price of any other single salt system worth its salt!
I decided to follow the recommendations of www dot troublefreepool dot com. For non-SWG, FC should be at about 10% of CYA level. For SWG, about half of that partly because of the super-chlorination in the SWG pipes. I am maintaining CYA at about 60 as recommended by that web site for SWG pools. So I am at 60ppm CYA and 3ppm Chlorine at the lowest point just before the SWG recycles. Despite using one tablet along with the SWG, I still have to add some acid once in a while. I am hoping the backwash and refill will keep the CYA in check, balancing the addition from the tablet.
However, I had to contact Intex customer service because the unit continuously displayed "high salt"--regardless how low the salt content. They were SO HELPFUL!!! They sent a new thingee (the part that generates the chlorine), and it's worked great ever since.
I LOVE INTEX products!!! While the products are not always perfect, they stand behind them and work until the issue is resolved.
