I realize movement helps break everything down. what if u are living in and not mobile? how do u dissolve it? I am using a chemical. I dumped my tank but I don't think it worked sensors says the same as before.

I have never been able to bring the sensors to zero or 1/3 even when I leave them open for a long time open. Don't trust does things, they are worthless. I disciplined myself to dump them every couple days and be on the safe side. NP

It's common knowledge the fluid level guages lie like politicians. I installed a sprinkler like tank flushing device into the wall of my tanks and now my readings are much closer to real. Things in the tank were keepin guages from accuracy. Or if you are a star trek fan let us say the cling ons were invading and were eraticated by the flush kit.
