Working in campgrounds, I have seen more than one tank completely clogged, where we had to use a rod to unclog it. I see no downside, other than a few cents a tank, to use chemicals to assist in breaking down paper and waste. But, I also have fire insurance and I've never had a problem with fire.
Disposable wipes are the worse, do nothing but cause issues.
