I remember a thread on what deodorizers people liked for holding tanks and portable toliets. I did a search on this site and did not come up with much. The product we formerly used is no longer available. We got a product from West marine and were not exactly thrilled with it. I wondered what seemed to work well for others. We use our portable throne for emergencies only. I wondered if anyone used anything like the disolvable tabs about the size of the dishwasher tabs?
