Get high performance reverse osmosis with Aquatic Life’s Twist-In 3-Stage RO Unit


One of the best investments for a dedicated hobbyist is the addition of a reverse osmosis unit to make impurity free aquarium water. But a quality RO unit can be expensive and a pain to change filters. The Aquatic Life Twist-In 3-stage RO filter is hoping to change that with 100 gallons per day output for under $100.

There is just too much in tap water that can wreak havoc with your tank and its hard to trust when a water treatment machine was serviced. But using your own RO unit helps keep things in control.

The Twist-In unit features a 5 micron sediment filter, a carbon block and RO membrane. Each one is replaced with a simple, color-coded twist-in cartridge. The micron filter and carbon block should be replaced every 3-6 months depending on the usage and how much junk is in your tap water, while the RO unit should give you 1-2 years of performance.


Each carbon and sediment filter replacement retails for under $10 and the RO filter retails for around $60. The entire 3-stage unit retails for $98.99.
