That was a lot of questions.
The pot is resin, or plastic, and has been in this tank for two years. There is no chance the color is coming from the pot.
There is no driftwood or colored gravel in the tank. The gravel in the tank is also two years old, and is natural with no artificial colors.
The water is tinted pink, but not cloudy. There are no plants, real or artificial, in the tank. There are no signs of any algae growth.
This change gradually occurs when we change water. We can see it roughly 12 hours later. It looks like someone took red food coloring and placed a few drops in the tank...just enough to tint the water.
We have had no recent change in food, fish, or anything in the tank.
The only thing I can see that helps is salt. If I add salt, the tint will disappear in a few days. The color will then reappear at the next water change.
Water parameters - pH, hardness, ammonia, nitrates, nitrites are all normal. We do not run carbon in our wet dry.
The fish do not seem to be affected, I am just curious as to what this is.
I will try to take a pic tomorrow in natual sunlight :o)
