I've search this site and read countless reviews on both CW and Amazon and I can't see which one is the best. Which chemical do you think does the best job and why?
We use the orange drop in tabs (Chemco - I believe). We also put a capful of Calgon in the tank before we put some ice in there (once we've dumped/cleaned the tank). The ice melts and sloshes around on the trip home. Our sensors still don't work but we have no odor either.
Someone mentioned the odor from the gray tank...we had a small spill from that tank at the house and it smelled 10x worse than a sewer. Wow!
