Holding Tank Treatments?

I use the monochem T-5... powder, formaldehyde based, no smell...

I get the thetford campa chem from walmart. No smell and makes a nice soup after only a few days...

Never had a smell...

I use Pure Power Blue. Have full timed for the past 18 months now and the black tanks go 8 to 10 days before needing to be dumped, have never had an odor and really breaks down TP and solids quickly.

GeoMethod for Black and Gray tanks. No bleach.

If you must, then bleach -- cheap, simple, and fast acting.

Decomposition in your tank takes a while...chemical or not. Personally I dump it every 4 to 7 days. Ponds or pods? If you want a mobile decomp RV, be my guest. I don’t.
