Lime Green Pool Water

[mbar]

Just another thought - before I learned what I now know about stains, I also had lime green water. It turned out that my white fiberglass pool was stained yellow all over. Blue plus yellow equals green! When I got rid of the stains the water turned blue. You can see if the pool is stained by lowering the level of the water and see if there is yellow on the part you can see.

Good point, Marie!

Pool surface colors can affect apparent water color a LOT.
