This is the special tube to circulate our 5 gallon RDWC bucket system. The tubing is 1/2 inch on one end to fit the pump and 3/4 inch on the other end to squeeze into back of bulkhead from our easiest RDWC system video. Please watch the video to see how it works, this does not include any printed directions. This is recommended for 1" circulation lines, using smaller tubing like 1/2 inch or 3/4 inch to circulate buckets wont let enough water thru and will cause problems like uneven water levels.
