Do Ice Cubes in the RV Black Tank Really Work?

Back in '03 when I purchased my used '01 Cardinal I soon found out that the previous owners, who never pulled it themselves and kept it set up at a campground all the time, kept the black & gray valves full open all the time. As you can imagine, there was a pyramid of poop in the black tank. Someone on this site recommended the ice method to break up the pyramid of poop. I tried it, but got minimal results.
Then someone, also on this site, recommended that I use liquid Calgon water softener. I poured about a cup or so of Calgon into the 2-3 gallons of water I put into the black tank when I put the deodorizer packet in prior to leaving on a camping trip. This, over time, did the trick of removing the great pyramid. I use one of those clear plastic connectors when dumping my tanks so that I can see when the black tank fluids run clear and think the Calgon helps to break down the solids and paper.
In regard to the sensors, I'd say that it helped to keep them clean, but over time (I've owned it for 11 years now) I admit that the sensors are not totally reliable.
