Thetford a trusted name

Thetford AquaMax Spring Showers 8-pack Dry Holding Tank Treatment - We have been using this product for many years. Thetford is a trusted name for RV'ers of all times. We are pleased to say that camping off the grid for two weeks at a time this keeps our holding tanks fresh and clean even in the summer months.

Better than liquid treatments

Live full time in rv. Found liquid aquakem was best brand for us then one day they were out and got the packets. So much better in breaking down solids and no real tank odor. We do use the rv trick of adding some cheap fabric softener to tank which also controls odor. We're going to stick with packets from now on.
