Possible the Vent Fan is sucking out of the Tank? We do not have the vent running until after the flush.

Your solar fan is pulling air out of your holding tank. It's doing that because there is an air gap in your toilet. Replace the seal or use plumbers grease to keep it from drying out. If the bowl refuses to hold water you'll have to replace the seal. For the last part of your question...I don't know of any holding tank chemicals that will harm your tank over time. Of course, read the label!

If the bowl is not holding water try using plumbers grease on the seal. Turn the water off, hold the valve open and apply grease to the seal. Unless the seal is really bad it will work until next year.
To me whether it is in storage or not, these packs are about a Buck each and smell good. Deodorant is better than sewer smell. I flush tanks every trip and rinse with wand but green or blue flush able is always the last thing with a few gallons of water.
Chemicals going down the pipe don't concern me much. They are also supposed to break down paper products.
Why hesitate using the deodorants? That is what they are for.

Interesting experience for us...

Last year while part timing it we did use chemicals because we got the sewer smell. Ball valve seal was fine but I *THINK* the vent system wasn't working well. That was our Winnebago.

3 weeks ago we went full time in our DSDP which has the older 360 RV vent caps that swing around in the wind. We don't use any chemicals nor do we have any odors. We just make sure we get 3-4 gal of water in the black tank after we dump.

I plan to replace those (IMHO ugly) Xtreme Plumbing Vents for RVs with the 360 RV Universal caps. https://360productsnorthamerica.com/site/home

Thanks all! Seals on toilet are fine and yes we leave water in the bowl.
We will check and make sure the solar vent is not plugged( we just installed those a few months ago).

All previous posts are good advice. For our two cents worth, we have used Happy Camper - Odorless Holding Tank Treatment Black and Grey Water for years and never had any sort of problem. You order it on line and will have it in just a few days. A great product!
