Holding tank Cleanout

[Solana Jim]

Any suggestions for a THOROUGH cleaning of our holding tank? We have pumped, flushed, pumped but still getting odors. Any good chemical additives we might try to flush and clean better?

We have had great results with Odorlos: https://www.amazon.com/Odorlos-V77004-H ... ds=odorlos

A charcoal vent line filter can also help reduce odors.

A charcoal filter is the way to go. There are commercial ones but you can make your own, my previous link will show you how. www.tugnuts.com/viewtopic.php?f=5&t=3921&hilit=+filter
I change the charcoal every couple of years and get no odors, when I do it's time to change the charcoal. No need to buy anything else.
