I have found that if you keep plenty of water in the tank, additional flushing isn't really necessary. If my tank sensor starts messing up I will rinse the tank when I get home. I bring a hose & high pressure nozzle into the bathroom, open up the flush valve, and let'r rip. Cleans up any residual stuff in the lower toilet also.
Thanks for the advice. All of it is good!! I will have to decide which to follow. I guess the easiest would be to keep plenty of water in the tank. The Flush King is something I would definitely be interested in. I do not kike to empty anything at home because I live in a residental community and would be run out of town.
