420 SCI Rez Block Cleaner

The All Natural Resin Blocking Water Pipe Additive

Just a few drops of RezBlock Conentrate will keep your water pipe clean.  How is this possible?  We use fruit and vegetable extracts that create a natural slippery coating that resin can't stick to.  The resin stays in the water instead of sticking to your water pipe,perc and downstem.  Just add a few drops each time you change your water.
