Tank Care & Chemicals

Sorting out RV tank care and chemicals

Three different jobs hide under one heading here, and confusing them is how a rig ends up smelling while the black-tank gauge insists it is full. Here is what each category handles:

• Holding-Tank Treatments — drop-in pods, liquids, and enzyme packets that digest waste and control odor in the black and gray tanks.
• Toilet Chemicals — treatments dosed at the bowl, plus starter kits, that keep the toilet fresh and the tank moving.
• Tank Sensors & Gauges — replacement probes and senders for when the monitor panel stops reading right.

Most owners spend their time in the first two categories and only reach for the third when a gauge starts misbehaving. Pick a treatment that fits how you camp, and treat a lying panel as a hardware fault rather than a chemistry one.
