Black/Gray tank maintenance
Has anyone ever tried Rid-X in your holding tank to help clean the sensors and tanks? Seems like a much cheaper way to get rid of the grime in the tank. Thanks for your advise.

TSP is trisodium phosphate, and typically comes (when or where available) in a box labeled "TSP". You might find it in a big box store in the painting prep/paint stripper area, if not in general cleaning supplies. Many places frown on it or ban it because they are trying to limit the amount of phosphates released into the environment (particularly into runoff).
