## Description

iSpring FA15 10-inch Inline Quick Connect 3-Layer Alkaline Replacement Water Filter Cartridge with Mineral Balls, Calcite, and Corosex for Reverse Osmosis RO System, White : desertcart.co.uk: Automotive

Review: Excellent so far - Perfect but little on pricey side to other options. I wanted something to add to my 6 stage RO system which comes out at zero for my reef tanks. As I now live in a very hard water area with no reservoirs the water smells and is awful up this way. Added this to the side to which I divert the water for drinking. Comes out at around TDS 82 perfect and even better with a slice of fruit.
Review: Remineralised at last! - I've had my 5-stage iSpring for several years and have been pleased with the taste. While I think we're not meant rely on our drinking water to get our minerals, sometimes I get questions of concern from guests. Word to the wise: best not to even mention that your water filter is RO. Sometimes people think it's distilled water. Ugh. Anyway, I bought and attached this sixth alkaline stage and did a before and after taste test. The 'before' was just as good as ever. The 'after', now going through the filter, has a slight brightness to it which, while not a huge difference, is to my taste buds preferable.
