This vendor does provide the correct carbon replacement or Salt free components for a Pelican water filter tanks. Both the carbon and salt free media is x3 smaller than my original Pelican components. The 1st run through my Pelican tank, with this carbon component, the smaller carbon mix of particular it passed through Pelican filter at the bottom feed tube. I was see carbon media in my house water. Had drain my Pelican tank as not to cause house water problem. Need to drain that tank next. Not recommend. Waste of time and money. The original carbon pulled from my Pelican tank, after 5 years, is still larger than what was sent to me. The salt free media that was sent is the same thing. X3 small particular.
