Personally, I made my own tank wand from some spare parts I had left over from other projects. I cut a female hose coupling off an old split garden hose and epoxied it into a 1" diameter x 30" long piece of PVC pipe left over from a sprinkler system repair. I used PVC cement to fix a 39 cent PVC cap to the other end of the pipe, then drilled three small diameter holes in the side of the cap.
When connected to a hose at a dump, I just insert the wand down the toilet after the tank has drained but while the black valve is still open. Then I twist it around to move the three water jets around the sides and bottom of the tank. Generally within 2 or 3 minutes after inserting it, the tank water is cleared up. I normally use it with my incredible shrinking, "as advertised on TV" Pocket Hose (from Walgreen's, not TV). The hose comes with a shut-off valve, so tank cleaning is now a one-person job.
