Digesters, Deodorizers and Formaldehyde
We are new to RV's, and am befuddled by the range of digesters and deodorizers on the market. My research has led me into the quagmire of the formaldehyde vs. no formaldehyde debate. Apparently, at one time, someone decided that formaldehyde was killing the aerobic (beneficial) bacteria in waste systems, and it was subsequently banned in many places. I am also seeing articles indicating how that has been proven to not be true, and that it is fine to use and the most effective product at eliminating odors.
At one local RV store, the unsolicited recommendation to us new buyers was to use Unique Digest-it (no formaldehyde). When we bought our trailer at another dealer, the trainer swore by Thetford's Aqua-Kem (formaldehyde), and the trailer came with a sample. He didn't seem to fear being unable to dump due to restrictions, but I was afraid to use it lest I wouldn't be allowed to dump it. Although not one anyone has recommended, I picked up the enzyme/bacteria digester at Wal-Mart since we were in there on our maiden trip (getting new towels to replace the ones soaked when I attempted to flood the new trailer, but that's another story). I used it that weekend, and experience no odor, and the tank seemed to dump easily, but it was only one weekend and the first use of the systems.
So what are others here using? (I saw one recommendation of Pure Power but haven't seen it in a store yet)
What is the latest info in the formaldehyde vs. no formaldehyde debate?
If I use the formaldehyde products in my tank, am I going to run into a lot of places that won't let me dump it? (The two RV parks here in NM we've dumped at so far stated no restrictions.)
