Urine Sucks!

Our Natures Head composting toilet has a urine container. This container is 2 gallons. We tend to fill it up about every other day. The first couple weeks living on the boat we over filled the urine several times. Its a mess to clean up.

When we pull up the seat urine spills everywhere. Then when we pull out the container it spills again from the bottom where it was soaked with urine, we have the lid on container so it can't come out the top. Then we take it up to restrooms and while pouring into the toilet, it spills everywherearound toilet   because it is so full. By the time we are done there have been many urine spills.

The composting head part works great, we put peat moss in and follow the directions, no problems. The urine on the other hand SUCKS! It stinks and over flows because we can't see the urine fluid line. 

So far we are using blue food coloring, dye did not work, so we can see the water line. This is working  well. The rancid odor we haven't found anything to help. We use brown sugar, but it doesn't seem to work. I've tried baking soda, it didn't do anything. Maybe we need bigger quantities of brown sugar and baking soda?
