Hey Kim,
I use a product called Refresh. Mix in 4oz with a gallon or so of water & put in the black tank. It may be the same blue product you mentioned. It has a strong chemical odor that is only noticable when the toilet is flushed.
The maintenance guy at the RV dealer told me that it has formaldehyde & many dealers/park owners frown upon it. Most other products have a formaldehyde-free formula that has bacteria or enzymes to break down the waste. He told me on our walk-through that he was a full time RVer & he did not recommend anything except the blue chemical. His reasoning was that the bacteria formulas needed a lot of time to work effectively & most campers only get used for weekend trips. He also said that the small tanks on the KZ would not allow one the luxury of time, ie. you would have to dump the tank before the bacteria had a chance to work.
Hope this helps,
Matthew
Edit to say that I have never been to a park that has mentioned anything about it so I am not sure about this statement. —- "many dealers/park owners frown upon it"
