The Intex Krystal Clear Saltwater System is one of the best selling salt water chlorinators on Amazon and is available in 2 models – 7,000 and 15,000 gallon units. This unit is designed specifically for above ground pools and requires a filter pump with a flow rate between 700 – 3,000 gph.

This Intex system is an extremely affordable and easy way to convert your pool to salt water. Forget about adding chlorine and messing around with measurements etc., this unit will look after your pool and deliver consistent clear water. It is capable of delivering 5 GPH (gallons per hour) of chlorine.

This system uses a unique two stage method to sanitize pool water. First stage is the typical generation of chlorine using the electrolysis method. The second stage, which is unique to Intex, is called ECO (electrocatalytic oxidation). This process takes water molecules and splits them into oxidants which destroy contaminants such as algae and bacteria. This second method is so effective that the amount of chlorine needed is reduced by up to 60%. The level of chlorine required is so low that it goes undetected in the water.

Installation is a breeze – simply connect the hose (1 1/2″ hose & connection fittings) from the output of your pump to the unit and then run a hose from the output of the chlorinator returning to the pool.


The Intex Krystal Clear Saltwater System is fitted with a cell self-cleaning function helping to keep maintenance low. Continuous operation can sometimes result in calcium build up on the cell plates but by switching polarity in the cell unit the build up is mostly prevented.

The chlorinator cell housing is clear allowing you to quickly assess the condition of the cell. Manual cleaning is facilitated by removing the cell plates and submersion in either an acid solution or a pre-made solution available from your pool store. For more information on cleaning cell plate, please read our article – How to Clean Chlorinator Plates.


The system is simple to use – set how many hours per day you wish to run the chlorinator for and that’s it. Note that you will need to set your pump timer to start 5 minutes before and 15 minutes after the scheduled run time of the chlorinator.

It also features a boost setting which can super chlorinate the pool in times of heavy use and a low flow / no flow sensor for automatic protection.


This saltwater chlorinator comes with a respectable 2 year warranty from date of purchase. Your receipt will be required to prove purchase date.

For the price of this unit, and the great warranty unit, it’s no wonder this is one of Amazon’s best selling chlorinators. Head on over to Amazon and check out the reviews left by many happy customers for this unit. Normally you would find cheaper units can be a bit unreliable but the number of positive reviews seems to contradict this.
