The original automatic feeder
This is the 1 oz version of Clack's automatic Res-Up feeder for homeowners and commercial Res-up/Rescare users with medium or high rusty or iron fouled water. This automatic feeder uses a wick to transfer your resin cleaning liquid into the brine tank/well. This is the original automatic feeder and hands down the easiest version on the market to use.
