We include a media funnel and a printed instruction sheet.
If you ordered a filter or a commercial water softener then the gravel goes in first and the media second.
We buy resin in one cubic foot bags so if you order a 1.25, 1.5 or 2.5 cu. ft. unit then the partial cubic foot quantities come in a clear bag that you can see through and not the original manufacturer bag. We supply you the EXACT amount of media you need for your system, so it all goes into the tank.
On twin units, we package the resin so that you do not have to separate it.
We provide gravel as an under layer for filters and commercial water softener but not for residential water softeners as it is not needed.
Note - we have not used gravel in residential softeners since 1965 so we have plenty of experience with this, and are very confident in it's effectiveness.
