flush aqua blue water, which is normal, but one toilet's water turns purplish brown. We are on a septic tank. Any ideas why the one toilet's water is such an odd color and is it a symptom of a plumbing problem?

No poop, Steve! City water--toilet is 19 years old (but so are the other two) PVC water lines
and the water turns the funny color within 10 minutes of flushing. The toilet is used regularly, but is closest to the septic clean-out pipe where the other two toilets are on the far side of the house.
Once the installation is completed, not much. The key is to cover the surface with water
plants. The plants keep the water cooler and shade the water so that algae doesn't grow. We found this out the hard way after many days of draining the pond and scrubbing the liner. Fish will nibble on the plant roots, so it isn't necessary to feed them. Duck weed is like a salad bar for koi. They can eat it completely, so I would get water hyacinths or lilies, etc. instead. Consult with people who sell pond equipment, plants, fish, etc. They are the experts and a great resource, especially if you are doing the work yourself.
