B. Semi-Automatic Cleaning

The Melody has a patented fully automatic reverse cleaning system which gives you clean, alkaline, ionized water every time you turn on your ionizer. With other brands on the market (and with Jupiter models less expensive than the Melody) you have to wait while they clean.
The Neptune will automatically go into a clean cycle each time you turn your ionizer on using the power button. If however, you simple turn off the water flow then your Neptune will go into sleep mode and will awaken when water is turned on again. If the power button is not used then there is no auto clean and you should manually clean your unit at least once every day.
The Microlite does not have a power button on the front but otherwise has cleaning functions similar to the Neptune.

C. Coral Calcium Port and LED Filter Life Indicator

The Neptune comes with an inbuilt coral calcium port (just like the Melody) and has a digital counter showing the estimated life of your included Biostone filter. The Microlite does not have a coral calcium port and uses four color bars that all light up when the filter needs to be replaced. The Melody has a full featured LED display and also comes with a coral calcium port.

IonLife now also carries the new improved Biostone filter for the latest Jupiter ionizers. This filter will fit in the Microlite, Neptune, Melody, Orion and Aquarius models and an optional .01M upgrade filter is available, The .01M Biostone is the finest domestic filter available anywhere.
