To make filling and disposing of RESIN with your DI TANKS easier and faster, you can prefill these bags with DI RESIN. 

This makes it much easier to load the tank (add the 'riser' to the bag before putting the bag in the DI TANK, and use your finger to make an escape route for the air under the bag as you push it into the DI TANK). 

The price is 'per bag'.
