Same here, we needed a new supply of treatment, so we bought 3 bottles from Unique. The local CW didn't carry it and by ordering several bottles the shipping wasn't too bad.

has anyone mixed calgon water softener with the normal RV Toilet chemicals?

I happened to do this yesterday before putting it in storage and the reaction created a large mass of jelly-like, white, opaque goo. I flushed with plenty of water... but have a feeling I will have to fill it back up and drive it around to clean that out of the tank.

What kinda of other chemicals are you putting in your holding tank ??

I use Calgon with Thetford Campi-Chem deodorizer with no problems.

If you have dried up drud on the sensors, you need to have the level of liquid in the tank over the sensor so that the liquid (and what ever you add to it) can dissolve the dried up crud. The tank could be squeeky clean on the bottom and still have dried crud adhering to the walls.

Then again the sensor could be bad.

I picked up one of those spray things that you put down from the top. Frankly I think I could make my own just as easily - a valve at the hose end - a length of PVC with a cap glued on the end and some holes drilled into the cap. I was hoping for some swiveling spinning high pressure sort of end on it.

Thanks for the tip. We just drove about 70 miles and followed the instructions on the bottle for first time use. We're leaving Thursday for an 11 trip where we'll be stationary for most of the time. That will give me time to fill and empty the tank 3 or 4 times before heading home. Digest It says that using their product and filling and emptying this much should solve the problem. If it doesn't, I'll probably fill the tank on the return trip with a heavier solution. After that I'll replace the damn sensors. Hopefully we won't have to go that far.

One capful of calgon water softner mixed with two ounces of TST Orange Power in about 1 gallon of water in the toilet.

Hmmm, interesting. TST Orange Power claims it breaks down waste and toilet paper, where the stuff I use (Thetford Campa-Chem) is only a deodorizer. Since Camping World also claims that TST "lubricates both your black and grey water lines", I believe I would leave Calgon out of the tank. Sounds like these 2 products are not compatible.

Would that include the now supposedly trendy PBR?

PBR? Peanut Butter and R?
Oh, Pabst Blue Ribbon.....I just got it. When I was a youngster 10 cent beer was Old Milwaukee. Pabst was not so cheap. i do remember getting caught drinking on the MSU campus and I was not yet 21. Uh oh.
