We purchased a 7 year old home and when we put water in the soaking tub in the master bath, the water turns blue. Could this be a special kind of tub? I can't find anything about it online.
I am guessing that you have a low pH and using copper pipes. Is that right?
If so, you would need to neutralize the water by raising the pH by a variety of different ways depending on the pH level.

Blue usually means copper in the water. A water test for copper will tell if it is the cause.
If it is, there are a number of causes; low pH acidic water, high TDS, DO and CO2 content, hot water recirculation systems with excessive velocity, dissimilar metals corrosion, bacteria and electric grounds on copper tubing or a bad building ground etc..
All can lead to pinhole leaks in copper tubing.

When we put the bath water into a clear glass, the water was clear. It only appears blue. This is what makes me think it's a special coating on the tub.
