Do I Want to Break Down Solids?

I was watching a video the other day about cleaning out the black tank. The video had a "RV Tank Cleaning Company" showing how to hydroblast the tank to really clean them out (black and gray).

In this the "technician" asked what type of tank treatments the guy was using and he outlined several he had used. The technician commented that you really do not want anything that breaks down the solids because it simply turns everything into "pancake batter" that causes problems with sensors. Really you want something that will control the odors, but the key is simply to use lots of water. He commented several times a RV black tank is not a septic system and it simply just needs to hold the waste not treat it. He even showed how to make a solution with Pine-Sol and Calgon.

It kind of makes sense, I do agree water is your friend. But, this is the first time I've ever heard of not wanting to break down solids in your black tank. Everybody knows these sensors never work; so, is this the problem that we are making "pancake batter" that is gunking up the sensors?

Honestly, I can't say I'm buying all this, but thought it would be an interesting topic to get others thoughts.

    Most people selling anything to do with the black tank are taking through the wrong end of the alimentary canal.. that is their words belong in said black tank. The sensors will work.. when the tank is new or when it's been completly cleaned. in short one time.. If you want sensors that work google SEE-LEVEL (With the hyphen) ther are other types of sensors that work better. I never did get around to testing HORST.. planned on it but it never happened. Horst is a "Traditional" sensor that works with your existing panel but is supposed to be more immune to "Sliming".

    The stuff WILL break down, no matter if you add $$$ chemicals or not.. Best chemical to use in your tank is water.
